SoaSE is a strange beast; too complex to be a RTS game, but too simplistic to be a 4x game (in the classic sense). Time will tell if it can carve out a successful new(ish) niche for itself.

As for revolutionary... What about Haegemonia? Imperium Galactica 2? Homeworld? Granted HW was a smaller scale, but this is just an evolutionary step up from those games (and one down from true 4X games).
