Wheel of Time

Wheel of Time was developed by Legend Entertainment and released in 1999. It uses an enhanced unreal engine, which is pretty obvious from the screenshots below.

The game can be played on all Windows OS up to Windows 7 (haven't tried on Win 8). Set to 98 compatibility mode when installing and running game. (for 64 bit you need to install on a 32 bit machine and copy the directory). There is a v333b patch but it is not essential to play.
