It's the idea though; the ability to take punishment and then recover if you don't get hit for long enough, instead of relying on health packs. It changed the whole genre, to the point where it's unusual now for an FPS not to have it.

You still need to rely on health packs in Halo ...

You are right about the whole it allows for less punishment on the player's end psychology ...

I guess it depends, if you use your shield well you won't need health packs, though that's easier said than done on the higher difficulties. I meant more in that it changes the whole way the games are played; we can be less cautious cos if we make a mistake we can quickly recover instead of having to go look for health.

The health bar meant very little in that game.  If you took damage with your shield down, you weren't likely to make it out alive anyway.  Sure you did occasionally, but the concept was there for others to follow.  Halo 2 did away with the health bar completely.

That's not how it was for me ... 

Wii Sports. It made gaming as whole "mainstream", expanded audiences, led the motion gaming crazy that later on influenced Move and Kinect, basically popularized the term "casual", made the Wii and itself part of the popular culture, and is the best selling game ever. Nothing tops that... Perhaps Tetris or Pac-Man, but they are from the past century.

Halo: CE

I don't think the Last of Us is revolutionary by any meeans. I just don't see it, sorry PS fans.

Halo and Wii Sports are revolutionary titles

Not bad points at all. Despite being very minor design choices, Halo did popularize them (it may have even been the first FPS for a two weapon limit?). It definitely altered FPS design for the better.

Why Mario Galaxy? Imean, it's a fantastic game and certainly innovative, but how was it revolutionary? What games did it influence besides its own sequels?
