Its about time someone else copied smash bros really.
Actually, several games have tried in the past. In fact, every single game that has attempted to copy the Smash formula has failed miserably.
Dream Mix TV: World Fighters, Battle Stadium D.O.N., TMNT: Smash Up, Cartoon Network Punch Time Explosion, etc.
All absolutely horrendous. As a result, I don't have high hopes for this game whatsoever. The problem is, Smash Bros., and Melee specifically, was good because of the sum of its parts. You can't take a couple things, leave a couple out so you don't get sued, and expect to have a game of the same quality.
