From Wikipedia article on Natural Selection:
Its innovative concept is a mixture of the first-person shooter (FPS) and real-time strategy (RTS) game genres.
From Wikipedia article on Savage: The Battle for Newerth:
The producers of the game, S2Games have coined their new genre as a 'Real Time Strategy Shooter', or 'RTSS'.
Um... In latter game's case, I think it's safe to say that combining first-person shooters and real-time strategy in 2003 was hardly groundbreaking.
Natural Selection came earlier, in 2002, but surprise surprise - that wasn't really the most super-innovative thing either!
Just what I said earlier - people were so awed by Battlezone that they can't remember the damn thing ever existed. Had Golgotha ever been released, that might have been just the same thing.
When will we see the first really popular FPS/RTS hybrid so that people can stop thinking this is new?
