Half-life and Half-life 2 are arguably two of the best games to date. While there are many other great games such as Diablo, Diablo 2, and I am sure that Diablo 3 will be a hit also. Games have changed alot since the first Wolfenstein to the new Doom 3 and Quake 4. Graphics have improved quite a bit. Even some of the free games that exist have some real good grapics. The next generation of games will be even more realistic. It will be amazing the day the computers are so fast that any game will run on any given computer and no upgrading will be need since the computer so far out paces the speed requirements of the games.
