Oh, dearie me, how have they upset me? Wall of text incoming.
*The Wii U only supports 1 gamepad. While this limitation doesn't affect me, as nobody I know wants to play Wii U games with me, this would suck hard for multiplayer. Of course, the limitation could lead to interesting gameplay designs, but overall this feels too limiting.
*Because the Wii U only supports 1 gamepad, if something happens to yours then you have to pay an exorbitant sum to get a replacement from Nintendo. Of course, this may just be because it's just crazy-expensive to produce, but maybe that should have been an indication to the Big N that the time wasn't right to release a console like this.
*Region locking. There's no reason to have this, except so you can charge some areas (like Australia) extreme prices for games. There is no argument that stands up to scrutiny for keeping region locking in place, except that some areas charge insane prices for games and you want to keep overcharging those areas.
*Wii U has no wired controller options for the vast majority of games. Most of the time, this doesn't matter that much, but for something that requires low response times, like Bayonetta, Wonderful 101, or Smash Bros., a few frames of delay can be a big deal. It's probably why the Wii U can't play Gamecube games either, if I'm recalling my Wii hardware knowledge correctly.
*GC adapter's availability. The lack of availability on this is completely inexcusable. They either knew it would be a problem but ran a limited run anyways to get the press talking, or they somehow don't have any knowledge of their biggest franchise's fanbase. Don't say "Well, they could have not developed it at all!". Nintendo knew that many people, myself included, would not have bought Smash 4 if you had to change to these new controllers. Nintendo also knows that Super Smash Bros. is a system-seller. There's no way to justify the shortage, and by the time they fix it, most people will have either lost interest or bought an unofficial adapter. Calculated greed or bumbling idiocy, this is pure failure.
*Amiibo availability. Okay, this one was kind of a shot in the dark, since they could have gone over very well or very poorly. But you'd think that they'd at least have some of the highly-in-demand Wave 1 amiibos restocked now, right? It's been 6 months now! Nintendo knows that these are sought-after items, and even the less popular ones are selling like hotcakes, and it would behoove them to renew some of these manufacturing contracts, but for some reason they're not. They're releasing cards instead, which is like an amiibo, except that I want to buy a figure and not a piece of cardboard.
*Amiibo functionality. This is pretty much on-disk DLC, the absolute worst kind. If your only defense of performing a ****ty business move is, "Well, EA and Ubisoft do it!", then you need to go stand in the corner and think about what you've done. Just because it works doesn't mean you're not a piece of **** for doing it.
*Amiibo functionality in Smash Bros. The average user won't care that their Amiibo can learn to play from them, or they won't think much of it except "neat". The high-level players won't care because they don't learn enough. They still act pretty much like CPUs, because the technology isn't there to make them think and act like a human player. If that's not enough, Amiibos get stronger as they learn, and by "stronger", I mean "hax". They get buffs to damage, knockback, and maybe speed, I'm not sure. Of course, for a high-level players, this makes them even worse than CPUs. So not only are they mostly irrelevant for their intended purpose, the way they were presented to the public is borderline false advertising.
*Amiibo quality. Nintendo promised high-quality figures of their most loved, well-known characters and delivered someone's deformed 3rd grade clay art project. Every amiibo I care about is deformed in some way. Sure, they look fine from 7 feet away at a bad angle, but when you closely inspect them, the shoddy molds are really apparent. Even stranger, about half of them have deformities that are unique to that amiibo. How do you mass-produce something where the entire run is seconds? It's truly a marvel of engineering.
*3DS has no games. Well, no physical games. It has plenty of hyped games, but most of them are still in Japan (see gripe #3) or eShop-only. I refuse to buy digital console games, because when the servers get shut down (like the Wii's and DS's already have been), I have to hope that my system's memory never gets corrupted or I'll lose all my games. I don't buy nearly as many PC games as I used to because you can't buy physical anymore. The only reason I even buy the few I do is because PC games are so laughably easy to pirate that I can be practically guaranteed to always have access to them, as long as I remember to back them up. Last I checked, there still isn't a way to play DSi eShop games, so if it's gone, it's gone.
*Nintendo's stance on IP. IP law is ****ed. It has been written by the businessmen for the businessmen, with no thought given to the average user besides "How can we squeeze even more money out of them now?". Thanks to broad laws lobbied by the MAFIAA, while Nintendo is technically within their rights to take down machinima and LPs, it doesn't mean that they're not being a really ****ty group for doing it.
*Nintendo's stance on IP, Part II: Shiver me timbers edition! I've bought a metric ****ton of games, and I've probably pirated about half as many more at some point in my life. Why? Mostly lack of availability or disposable income. No matter how much money you have, there's only so much of it you can spend on games. There's also a lot of rare and obscure games that are hard to find, or if you do find them you'll have to pay collector's (read: insane) prices for. A good example of this is Xenoblade. I was lucky enough to buy Xenoblade when it was new, but if I hadn't, I wouldn't have hesitated to take a frigate down to the Pirate Bay and check it out. Sure, there's a 3DS version now, but at the time I would have laughed at anyone who tried to tell me that there'd be a handheld version of such a massive game in as little as 3 years after its NA release. I've also gone through less-legal means to find games I'd lost. I know they're around here somewhere, and I've since found all of them, but it was either that or no game. How about my version of Xenogears? It doesn't work anymore, thanks to label-side damage. It's a perfectly legitimate copy, but critical files are damaged in at least 2 places. Thanks to TPB and disk swapping, I can still enjoy my favorite game. Yes, it's on PSN, but the PSN version has problems. Even if I bought the PSN version anyways, I'd have the same problem as before when my hard drive crashes and the PS3 servers shut down.
*Nintendo's stance on IP, part III: This went off on a tangent, here's me bringing it back together edition. Putting all that aside, it's incorrect to assume that pirates and paying customers are mutually exclusive. I've gotten into several franchises I would have otherwise passed on had I not taken a trip to the cove to see what's what. When something really impressed me, I not only made a point to buy other games in that series, but also to check out some of the studio's other games, too. More than that, I'd recommend it to all my friends and advise them to buy it. Where am I going with all of this? Strong copyright is completely indefensible. Not only is it a really scummy practice to stop fans from celebrating your work, or to charge them for the privilege to do so, even the rhetorical basis for these ridiculous laws doesn't hold up to scrutiny. Nintendo's continued support of these absurd rules, and aggressively using them to squeeze money from us after we've bought their stuff, shows how little they think of their fans. At this point, I see Nintendo as little better than EA or Ubisoft, and I've been boycotting them for years for a lot less. I don't know about you, but I'm not going to buy whatever Nintendo's next system is, whether it's a handheld, a console, or some ******** phone app (by the way, **** you for abandoning your hardcore fans for the casual babbies. Thanks for speeding your own demise, the industry doesn't need another scumbag EA/Ubisoft knockoff.).
