(3 days after release) It needs a lot of refinement, fixes, balance and more competitive stages, but i don't mind the visuals, the gameplay groundbase, while I prefer miles more a Melee/ProjectM, it's much much better than Ultimate and the developers don't actively want to kill the scene.
So from a competitive pov, is gonna be a thumbs up in half a year when it costs 20 bucks and the mayor stuff is fixed, but right now if you have some friends playing and you don't mind the high price I'm not gonna tell you "don't".
