I have TONS of crappy PSX games I didn't buy to play. I even have Hooters: Road Trip, V.I.P. and Irritating Stick. I've come close to buying Steel Harbinger many times and have the Saturn version of Criticom.
I don't think Hexen sucks. Actually, I have both the Saturn and PSX version. I just find the PSX one hard to control given the default controls, and the shitty controller.
