The game that perfected the modern 3D platformer is still great!
Super Mario 64 was the first 3D platformer that truly worked, and honestly it's surely still one of the best. I can't claim to be an expert in 3D platformers, I've only recently started to play them again after a 10 year hiatus or so, but I can tell you that Super Mario 64 is still infinitely playable today, no questions asked. All of the stages are absolute pleasures to play in, it sometimes seems like every moment you spend jumping and flying around is filled with pure bliss. The controls are spot on, the graphics, especially on the Wii with the higher resolution and 480p, are superb, and the music and sound effects, albeit simple, are easy on the ears.
However the camera isn't really good. I suppose at the time it was still an improvement over other, similar games, but in 2010 it is such a pain in the ass. I shouldn't have to manually move a camera around, it sucked back then and it sucks even more today. You'll die a couple of times in this game because of the camera, believe me.
However it doesn't detract too much from what is otherwise a perfect game. Highly recommended, it's a steal for 10$ on the Wii!
