Prey and Duke Nukem Forever fall into the exact same category. Games which were pitched as "we will make the content on somebody else's engine", but which felt they had to play catch-up on engine tech.
When id released Quake 2, they caused an absolute cataclysm for many developers. In terms of looks, it was way ahead of the Quake 1 engine, particularly for people with new-fangled 3d video cards. Lots of people were out there making games on the Quake 1 engine, with contracts that gave them cheap access to the Quake 2 engine once available. The assumption had always been that porting from one to the other would be easy.
It wasn't.
So several studios, including those making Daikatana, Prey, Half-Life and Duke Nukem Forever had a choice between putting out a game on the old engine or restarting a lot of their work from scratch on the new one.
The ones who went for the latter option ended up in engine hell. Only Valve came through it reasonably well. They took a hit on Half-Life's release date, but basically hacked around the Quake 1 engine to replicate some Q2 features and to make the (highly successful) bastardisation that became known as the Half-Life engine.
