I think it's ironic that Sakurai took away the depth to make people feel better, but with the depth gone, people who lose will actually feel worse. At least in melee, when you lost, you knew you could try and get better to not lose again. In brawl when you lose, you feel mad because you couldn't do anything about that tripping/landmaster (But with Pit I can almost not get killed by it 100% of the time, or at least not get killed twice by it!).
I like depth in a fighting game, it gives you something to continuously strive for. That's why we played Melee for so long, right? Even though I never learned to wavedash, I still remember playing till 3-4:00 in the morning with my friends. Now their favorite chars from melee are radically weakened, and we just don't feel like using/relearning them. So yeah, even though he tried to make people feel good, he actually made more people sad.
Funny how that works, eh? Maybe if he thinks of that, the next SSB will have some depth to it.
Plus, who hasn't seen that video of Daigo's Ken vs Chun-Li, where he has almost no health and perfectly parries Chun-li's super to take the win? It's stuff like that we want to strive for, so even if we get there just part way we feel good =P. This was an afterthought after I wrote everything else, and I don't feel like taking the time to make it fit the rest of the post.
