Oh definitely the one on GameCube. The controls were absurd.
I haven’t played the new version, but I had just beat it again on GameCube a few months before they surprise dropped it on the switch, so I wasn’t really interested. I thought it was the trilogy when it popped up on my screen and I was so excited, then immediately bummed.
Been playing Prime 2 on Primehack and that controls perfectly, I just don’t much care for the game. I really want to. It just doesn’t grab me like the first one. That’s coming from a Metroid fanatic who routinely replays all of the side scrollers haha. I just did it again like a month ago.
I just played through the Prime-hack version on PC, and the mouse + keyboard combo is much more natural for me to enjoy it. Morph ball mode is still a bit difficult to control, but it didn't bother me so much that I couldn't still finish the game at 100%
Updated textures and HUD and widescreen with a custom field of view were also big improvement
