Yep there are quite a few on this list: https://en.wikipedia.org/wiki/List_of_Unreal_Engine_games

Unreal Engine is the most used Game Engine in the industry (not counting indie/mobile games w/ Unity), especially for AAA games. HeartBreak shared the list. For professional development the Unreal Engine makes it possible to make amazing games with a small team of programmers, iteration time is fast making development a lot faster than before or trying to use a custom engine without well developed tools.

One reason for this is because a game engine is so huge and complex that they have a massive learning curve, much more so than any web framework.

If you use Unreal Engine / Unity, you have a pretty big pool of talent that is already proficient with the engine and can hit the ground running, rather than having weeks of learning the intricacies of your specific game engine.

you're kidding, right?
