Curious if some of the many internal AAA engines out there might start to get shopped around as a new alternate to UE. Sony, Ubisoft, and Microsoft all have a few in house engines that at least on paper seem viable for branching out — the biggest obstacle would be support, I suspect. Which isn’t a trivial obstacle, to be clear.
idTech is due for a resurgence. Maybe Valve could even get a revival in usage of Source.
