What bugs me about IGN, is how nit picky they are sometimes.
That's the job of a reviewer.
As a reviewer, you can't look at the game and say "Well, this part was disappointing, but this part was awesome, so we'll forgive the first part."
This applies to several things in Brawl. e.g:
1. Graphics. The graphics are beautiful. 60 fps. Great backgrounds. Great models. But there are times, especially with some of the pokemon and ATs, that the graphics are kinda "meh". Unfortunately for Brawl, the game as a whole looks so good that those small imperfections
really stick out. It's not that they think the game has bad graphics--in fact, they keep talking about how beautiful it is--it's that it's inconsistent. I still think 8.5 is unduly harsh, but meh.
2. Online. Every time someone gripes about online, someone else jumps in and says "You should be glad we even have online!" That's now how reviewing works. Yes, a game has online. How does it match up to other games which have online? In the case of Brawl, very, very poorly. To be honest, the wifi "with anyone" may as well be a restricted mode with slightly more advanced computers. 2 minute time matches... not too impressive in this day and age. Lack of ranking system, even though Sakurai had his reasons, is also a mark off.
3. Single Player. I'll admit, I haven't played SSE. It's definitely interesting to me. But to be honest, it really does look--as IGN said--like a platformer with arena-fighting controls. Adventure mode was pretty gimmicky in melee, and I'm hoping SSE doesn't turn out quite that way. In some ways, though, it seems like Nintendo Fanfic or something.
4. Loading times. Next-gen games shouldn't have loading times like smash. Halo 3 and COD:4 had some rough loading times, but they were masked really well by on-screen activity.
This was a well done review, and I'm quite impressed, to be honest. 9.5 is a good score these days from IGN.
Oh, and as for the fact that they said it's better than melee, yet scored it lower...
Sequels have a lot to live up to. It's better, but is it an improved formula or a whole new take? A good example would be Halo 3 vs Call of Duty: 4. Halo 3 improved on its predecessors, adding to it, taking from it, etc, while CoD:4 was a whole different game compared to its predecessors. Smash seems to be somewhere between the two extremes.
