Decent enough. I like the art design. But the game is way too easy and the open format flattens out the difficulty curve until the very end, until it suddenly spikes at the very end.
People who say Mario 64 has aged poorly are dumb babies. Its movement is still the standard we hold all 3d games to. Yeah the camera is bad, who cares.
The hardest game in the whole series and not for good reason. It is frustrating and generally very oddly designed. There's good stuff in here, I like the movement, but most of the game is kinda bad.
It's like the DS game but with two many autoscrollers and worse level design because it has to accommodate four players at once. It made me and my siblings fight so much as kids that my parents had to hide the game from us.
I actually think this one is the best of the NSMB games. It just has generally better designed levels and my favourite of the 30 billion flying powerups. Still kinda whatever.
