I never played any Smash Bros, so I have no comparison, but I grabbed this the other day, and whether it was a focused 1 on 1, or a 4 player free for all (all local - not online) we had an absolute blast! Really great party game for casual gamers.
So much chaos and zaniness, even someone who isn't a gamer can start having fun and pulling off supers in a few minutes, and yet, it still has enough depth where the person who's the most skilled (my younger bro) was the winner 7/10 times.
I approve of this message.

Anyway, I agree completely TC. I'm having a blast with this game, especially playing it with my brother. We're having a lot of fun fighting randoms online, or even our friends from our hometown. I haven't played a game this addicting in a really long time. :)
