Fallout 3

Many have tried but this is the first post-apocalyptic game which really makes you feel like you are in a nuclear wasteland. Fallout 3 lets you explore the huge world of blown-up buildings, radiated pools, evil raiders lurking in scrapyards and super mutant behemoths that take a mini-nuke to take down. You control your own destiny in this game and can choose to be good or evil. For example, in the early part of the game, you can choose to disarm a bomb to save a town. The best part is that you can kill your enemies in many ways. Go conventional with handguns, rifles and shotguns; aim for accuracy with energy weapons; go bada-boom with rocket launchers and mini-nukes. You can also be an explosives expert and lay mines and sneak up to the enemy to drop a grenade in his pants. Or be Bruce Lee by being a master in unarmed combat.
