Quoted from zombywoof:
I've never played any of these re-released Mario titles the first time around. I didn't have any of the Nintendo systems between NES and Wii. Do they have two player cooperative mode? If not, I'll just stick with Odyssey (I do not consider playing the hat a two player option).
I believe Galaxy had 2 player but it was not good. I believe one person would just point at the screen to collect star bits.
Skip Mario 64
DO NOT SKIP Galaxy. I said earlier in this forum that Odyssey is a better game for what it is but Galaxy hands down is my favorite game ever. It is pure Nintendo magic. Try and 100% that game. You will come out a better person. It is not easy to do. And then after Galaxy 1 get Galaxy 2. Its not better or worse but also magic. Yoshi is fantastic in that game.
