I didn't like Smash Bros. that much. In fact, I bought the game and sold if for store credit two times. I just couldn't get into it. All of my friends loved it, and I always got my butt kicked.
Still, the aspect of playing alone to get trophys and stuff, doesn't work for me.
What I would really like is Nintendo to get Capcom to Publish more 2D fighters on Nintendo (Home) Systems. Through the N64, I never had a 2D fighter, so I had to pop out my Snes to play Street Fighter 2. On GameCube theres only ONE 2D fighter (that I know of), CvsS2EO, which is good, but not on par with the Marvel vs Capcom games. Why couldn't the N64 have all those 2D fighters? Why did we get just ONE for GameCube?
