Alien 3 for the Genesis got rented nearly every weekend by me and a bud of mine, we could never find it for sale though. Great, great game. I also got AvP for the Jaguar, but to be honest I didn't care for it too much. However, it was several years after it was released, and I could see how I would have been nuts over the game had I played it back when it was new, but like the 32x revision of Doom, it's barely playable today.
It's not really an Alien game, but Alien Crush on the TG16 is a pretty good pinball game that is obviously influenced by the movies. The "table" reminds me a lot of the last level of Contra.
