Are there any current games using unreal engine 4? It seems this has been hyped for a long time but no real games have come out.

[Impossible]

The engine is pretty new, so most games that use it are currently in development. The current #1 seller on Steam , ARK (http://www.playark.com/) is UE4 based and it's already generated $10 million in revenue after being in early access for 1 week (http://www.gamesindustry.biz/articles/2015-06-09-ark-surviva...).

Some high profile games that haven't shipped yet include Fable Legends, and the new Gears of War from Microsoft, Flood in the Flame, Street Fighter V, Tekken 7 and Eve Valkyrie. Epic is working on at least two games, the open source community driven Unreal Tournament and Fortnite. It's pretty successful for an engine that has only been widely available for a little over a year.

...but with trail blazing on a new engine, come some pain points, as this post about ARK's terrible performance points out: https://forums.unrealengine.com/showthread.php?72345-Ark-Sur...

To be fair; if you're not a AAA developer with a good team running a multi-year cycle, I'd be pretty hesitant to recommend UE4 for a project right now.
