Gex 1 is my favorite in the Series. However, proceed with caution if you want to play this version. Controller support is limited, it runs at a sickeningly low resolution, and it's capped at 30fps compared to 60fps on the console versions (not unplayable or anything, but worth noting). Not to mention this version also has the same password system as the PS1 and Saturn ports, as opposed to being able to save in the 3DO version. But for the price, this is an absolute bargain. As long as your controller works, and you're willing to jot down passwords, this is dirt cheap. Don't miss out if it's on sale.
