gameplay is great.
...but the menus lacked polish. match modes were limited. single player shallow. in game items too few.
i hope they return to the series. and even though it would get flack for copying they should probably copy smash's damage based gameplay. i don't really get the hate for supers but it's obvious a ton of people didn't like. give it some more polish and i think the franchise can at least grow. it's a once a gen type title imo so a bit of a hiatus isn't a bad
