I like how none of those games listed have really changed videogames much at all. If you want to look at ground breaking games, I would look at Mario 64, Half Life, Halo, etc.
Mario 64 set the standard for 3D platforms. It was one of the first and still a solid game. Before Half Life, FPS's used crappy keyboard controls. Half Life was one of the first games to utilize the mouse as a means of looking around. I would also like to list Half Life 2 because it was one of the first games to really utilize physics. Half Life 2: Episode 1 also introduced HDR which is now in virtually every game. As for Halo, it was the first decent multiplayer FPS by console standards. Another game that comes to mind is Gears of War. It introduced a streamlined cover system that is now in all kinds of games. Finally Grand Theft Auto 3 introduced the possibilities of large sandbox games though I argue no other game company has come close to GTA's sandbox quality.
Pikmin is a great series, but I can't see how it's been very influential. I've never even heard of that Gundam game. I guess Animal Crossing would be the only exception on the list because it's the earliest example of a truly successful game that captures the nonhardcore gamer market (i.e. the casual gamer). These are the same people who bought the Wii for instance. I also don't know why Disgaea is on there. Aside from being a grindfest, there seems to be nothing special about it. I would imagine that the original Final Fantasy Tactics game makes more sense considering it was probably most people's first introduced to tactics games.
