-While I prefer Melee's mechanics as a whole/for serious play, I still find Brawl's mechanics very enjoyable even in a more serious setting, and as a whole, I think Brawl is a much, MUCH better game than Melee. It just has so much more content and the cast is way more diverse, in part because there are MORE characters, and in part because of the fact it cut down on clones.
-I didn't own any Smash game legally until Brawl came out. Before that, I practiced in Smash 64 in an emulator. I started playing before I ever bought a PC controller, so I actually became really solid with keyboard controls.
-While I have a fair bit of sentimental nostalgia for Smash 64 and a LOT for Brawl, I have next to none for Melee. I still enjoy the game a lot though, and think it's better than Smash 64 overall, and better than Brawl for when I want to play a highly technical match.
-A couple of months ago, I could wave dash and L-Cancel really well in Melee and Project M, but due to neglecting to play them for a while, I can no longer do either effectively, as I discovered when I tried to play Melee the other day. And in general, my Falco game has seriously deteriorated. It's safe to say I can't play especially well in Melee anymore...
-I think Super Smash Flash 2 is as good as any of the official Smash games and I think it deserves it's very own sub-forum here on Smashboards, since Project M got one.
-I'd totally love to see Black Mage in Smash 4 with his exact moveset from SSF2 and similar animations to what he has in that game. I think what they did with him in SSF2 not only makes him a strong fighter with a creative moveset, but one of the most charming examples of how Smash can turn an otherwise cute but fairly soulless mascot, into a completely loveable and endearing character.
-While a lot of people thought I was against Pac-Man being in Smash 4, I never was. I merely felt that he wasn't needed to complete any sort of "big 4 mascots" thing, I thought Mario, Sonic, and Mega Man were a complete trio, and I don't think he is nearly as respectable as the other three, despite being one of the earliest video game mascots, since his franchise has had no real staying power with nothing really keeping people interested in it (yes, Sonic had a rough time once and was only coming out of it before Brawl, but the games still interested people in SOME way, and the character is just really endearing to so many people and has a surprising amount of depth and likability, and he's also well known for his TV shows and comics. And while Mega Man has been getting the shaft from Capcom, there is an obvious demand for more Mega Man games by the public). I was also rubbed the wrong way because most people wanted him for that reason alone, and not because they had creative ideas for movesets or because they even genuinely loved the character (and I never expected people to since Pac-Man is really a soulless mascot character and anytime he's had anything resembling a fleshed out personality to speak of, nobody has really liked it, e.g. Ghostly Adventures). That all being said, I really like Sakurai's take on Pac-Man and I'd go as far as to say I'd love to see him make a Pac-Man adventure game, since I believe he has the power to breathe new life into Pac-Man as a franchise, much like he did to Kid Icarus.
-Subspace Emissary was one of my favourite things to ever be added to the franchise. It had some flaws, but overall, I believe it to be a successful, worthwhile addition to Brawl, and it is a hell of a lot better than Melee's "Adventure" mode (especially since Melee's Adventure mode also made Classic Mode feel redundant). I also don't understand why people dislike the Great Maze. People complain that it's too difficult, too long, or too tedious, but I felt none of these things. It can be completed in 2-3 hours and there are plenty of save points if you want to take a break from it. Honestly, the Great Maze was just as fun as the Great Cave Offensive from Kirby Super Star, if not more fun.
-When Sakurai announced that there will be no story in Smash 4, I was extremely disappointed. It actually killed my hype for a while. However, Rosalina's announcement put me back on the hype train, and she's still one of my most hyped aspects about this game. I haven't been this excited for a character since Sonic being announced for Brawl (with Mega Man being a close second, and Palutena being third).
-I'm actually really excited for Amiibos and am satisfied with their implementation into Smash as they stand now.
-I'm more excited for the prospect of playing Smash Run online than I am for playing regular matches online, at least in relation to the 3DS version.
-I own a physical copy of Melee and Brawl, but I don't own any legal copy of Smash 64.
