Yeah, seems like. Like when I was a kid and I played Dune 2, then played Warcraft a few years later, the one seemed to inherit most of its ideas from the other.

But I didn't like go look up the dates or exhaustively check that no other game came up with the format first. I know the first Age of Empires is somewhere vaguely in that same time span too, but I'm not certain of the order.

Thus seems.
