5: Tom Clancy’s Rainbow Six
Another classic, and the allfather of the realistic-style shooter. Rainbow Six was a hardcore game for hardcore people. One shot and you’re down. Not too long and your entire team is down. Waste ammo? Too bad. No refills. Plan an assault, execute it slowly and thoughtfully and then maybe nobody has to die. Well, except the bad guys. The game was developed in close cooperation with military fiction author Tom Clancy, who’s novel of the same name was actually only finished after the game had gone gold.
