CryEngine was shilled as a free* multi-purpose game engine way before UE4, they failed miserabley because no documentation, middleware like Scaleforms require licensing or reimplementation. In the end they sold CE3 to Amazon, they made a few MMO and abandoned it too. CE5 is a meme for CryTech only
IdTech was pushed as a multipurpose engine during gen7-8, and they failed too, now it's only an engine for FPS for 2 studios
