Most Influential Games

[TinCow]

Wired has an interesting list of their top 15 most influential games of the previous decade. It's particularly thought-provoking, because influential is not the same as successful. The criteria are summarized as "games that made big leaps and defined what would come to be traditional aspects of the big-budget grand adventure, and others that pushed the reset button on game design." Here's their list:

1) The Sims
2) GTA 3
3) Guitar Hero
4) World of Warcraft
5) Brain Age
6) Halo
7) Bejeweled
8) Wii Sports
9) Geometry Wars: Retro Evolved
10) Metroid Prime
11) Silent Hill 2
12) Half-life 2
13) Metal Gear Solid 2
14) Happy Farm
15) Portal

There's a lot of decent stuff there, but there are several omissions that I consider as significant milestones in gaming since 2000.

Diablo 2 - Showed just how much entertainment value there was in online action gaming, and fundamentally changed the entire notion of how to reward players for their game time. Was also a major milestone in online gaming, giving a major boost to MMOs.

Tribes 2 - Introduced vehicles into FPS games in a way never before encountered. The successes of the Battlefield series built off of this game.

Medal of Honor: Allied Assault - Redefined the concept of the scripted event. While the MoH-style scripted levels are now often considered rather boring, at the time it introduced a level of immersion into FPS gaming that had not previously existed. The sheer number of games that adopted this style of level scripting shows its influence.

Farcry - Upped the ante on the open-world FPS concept.

So, what other games can you think of that have changed the way games are made over the past 10 years?
