People have been saying this since Half Life 2, possibly even longer, then everyone said it about Crysis. To be fair, Cryengine has some validity as a future proof engine. It was first made in 2002, just 5 years after Gamebryo and is still being used in heavily modified forms by a large number of studios. But even that is showing its age and is getting heavily refactored yet again for the Open 3D Engine that the Linux foundation is working on. With that said, the amount of active development and intensive refactoring that the Cryengine has gone through at this point eclipses what has been done for the Gamebryo engine. But it still seems like lack of respect for tech debt is the larger problem than “just switch engines”
Yeah, because Microsoft/ZeniMax/Bethesda is such a small corporation and Fallout/The Elder Scrolls is such an inconsequential, low budget franchise.
