I’m fan of Unreal game series which are based on this engine. Unreal Tournament 99 even after 24 years is a good game. I’m still playing it on weekends as well as other games from this series. I’m not sure what someone used to OldSchool look could say about Photo Realistic graphics, but anyway somehow it’s good to know they still working on. 
The only bad thing is that they stopped working on Unreal Tournament 2014 (based on Unreal Engine 4). I wonder how it would look like on the latest version of this engine. It’s 9 years already, but I still remember the news about it’s pre-alpha version.
