System Shock 2 | GOG | 89p
Long before Bioshock became the darling of gamers everywhere, PC gamers were catching early signs of Ken Levine's talent with this series. System Shock 2 is widely considered an atmospheric masterpiece and one of the scariest first person shooters around. And for 89p, you may as well give it a shot. Hell, I'm not a PC gamer, but at this price I'm tempted to see if it'll run on my laptop.
