Halo
A game that deserves better than the Xbox. An amazing game that will soon be coming to a 3.06ghz, 512mb RAM, ATI Radeon 9700pro and Audigy soundblaster 2 equipped PC near me, with a 6.1 speaker system of course. And with Breed, the just-as-good-game-with-better-graphics too.
D&D
I say again, an excellent role-playing game. Slightly modified, it is also an excellent training program for negotiators, generals, hostage rescue units, rescue units, crisis units, the police, and the army, not to mention any other job that requires patience, intelligence, and a bit of luck.
M-16
Quite possibly any of a large variety of such rifles, the most widely known one being the M16A2, which was first introduced during Vietnam. Despite popular belief, many varieties of the rifle are not automatic, though special varieties do come with optional full-automatic firing. The standard M16A2 of the Army is not automatic, though.
