I do not at all care for this game's competitive scene nor can I do the glitchy tech that competitive players do, but from a casual standpoint it has a good amount of single-player content. It has the best version of the target tests, a bunch of cool, unique trophies to unlock, a handful of modes and a few minigames, a roster twice the size of the original game, a bunch more stages, and the classic & adventure modes are enjoyable modes to play through. Compared to Smash 64, it's a big step up, but compared to Brawl and other later installments I'd say it isn't quite as good. It still excels in some aspects compared to them though such as having the best trophies and target tests.
