Fantastic game. I have a full version arcade machine of this in my living room.WanderFreak said:Revolution X
Granted it's more rail shooter, but it was first.
For me, it was Doom I believe, but I only played it a couple of times. The first one I played consistantly was Quake 2, specifically Loki's Minions CTF mod online. I played mostly RPGs and Racing titles back then.
