I guess I was just clarifying that the OP makes a comment implying "Epic made a game engine and blockbuster game all with smaller staff".. but the blockbuster game kind of.. takes away from the point because it already existed. the comment stands stronger simply on the fact that Epic made a better game engine with a smaller staff.

I think the point is that software development is generally a continuous process. I highly doubt they've completely stopped all active development on Fortnight.

DOTA was a WC3 mod but the rest are new games built from the ground up in that established genre.
