>>712373510 (OP)In terms of pure gameplay, Galaxy 2 is probably the better game. But Galaxy 1 is better in almost every other category. The observatory is a more memorable hub area that feels more fun to explore. The Starship feels like it is just a resting area where you stop before picking between going from point A to B. Galaxy 1 felt like it was trying something different with Mario, taking him out of his element, and putting him in a grand space adventure. 2 doesn't even feel like it takes place in space anymore. It's like every other bright and colorful Mario game. Galaxy 1 had you traveling outside of spaceships and was always accompanying with that dark, starry sky box.
I think it's the same thing with how DMC1 fans prefer over the others because of its aesthetic. I prefer every other 3D Mario in terms of gameplay over Galaxy, so that makes picking 1 a little easier.
Also, as a kid, I never liked the Cloud suit. I didn't like how it made Mario floaty and I felt like the game overused it compared to other power-ups.
