I've played for a few hours, enough for me to pretty much dominate every match because I am amazing at video games.
Things I like:
+ Amazingly good netplay. I've been playing people in the US and Europe from here in Japan and it works very well, and does a great job of negating and hiding lag. It feels very much like GGPO (rollbacks) and I wouldn't be too surprised if I found out if it was using its secret sauces.
+ Both controller and arcade stick work great.
+ Three attack buttons with different attacks for up, down, forward, and neutral mean characters have a LOT of moves each.
+ I think I like static knockback a lot (as opposed to Smash Bros variable knockback). I like Killzone guy a lot and I feel like this gives me a dependable zoning game. This might also mean dependable combo setups, too.
+ As I predicted, due to the scoring system, ganging up and kingmaker shenanigans just don't work. If I'm better than y'all motherfuckaz, y'aint stoppin' me.
+ Levels shift around a lot. It's cool.
+ No random bullshit. You can see the bullshit coming
Things I don't like:
- The bad kind of button config, where you have to scroll through the commands instead of just hitting the button you want. And you have to be an online match to even change your controls! I'm sure this will go away by the time the game is done, but lol.
- Why is item pickup its own button that I have to configure? You don't want people to pick them up accidentally or something? I'd honestly rather have down+PPP like Cody in SF4 or something instead of another button. Eight buttons is a lot to configure! Along these lines, you could just make throw attack+guard as well.
- No offline or practice in the beta. Oh well, it's a beta!
So overall, I like it a lot (even more than I thought I would) and I think it's already clearly going to be a better game than Brawl. Deal with it.
