Honestly it seems like it always has: there are a handful of dev houses using their own engine for a spread of games (e.g. EA with Frostbite, Ubi with Anvil, Rockstar with RAGE, Bungie with whatever they call the Halo/Destiny engine these days), then UE or Unity are out there mass licensed for a whole bunch of stuff, then the few less widely licensed engines like Source.

That's not how it always has been. Licensing engines was virtually unknown 30 years ago (and when it happened at all it was within a very narrow range for making games in the same genre, more like asset swaps and level packs than outright new games), and new and exciting in the '00s.

Yeah sorry I meant from, like, 2000-ish and on.
