If by revolutionary you mean what games are most emulating it, then out of those, Gears of War. However, RE4 influenced Gears of War, so then my answer would ultimately be RE4.

I know it was cited that RE4 inspired using 3rd person perspective, but they have little in common other than both are 3rd person.  Gears of War's key mechanics are cover based shooting, and moving from cover to cover.  Those are features that are inspired by other games (Kill Switch) but mixed in an evolutionary way in Gears of War.

Many of the list have evolved their genres and inspired others.  Personally I went with Gears of War overall, for evolving cover based shooting, co-op play, and several interesting multiplayer modes.

I might be wrong here but is Gears 2 the first game with a horde mode. It seems every multiplayer shooter since has one.
