"We first heard about XreaL about a year ago, but it is gone mostly under the radar. It sounded promising at first, but like so many open-source projects, they often end up being ill-maintained and fade away as quickly as them come. However, we were ecstatic to learn a few days ago that the XreaL project is still along and that this engine is growing to become quite an interesting engine for first person shooters. XreaL is in turn based upon the open-source id Tech 3 (Quake 3: Arena) engine, but so many changes have since been made that no longer makes it look like an engine from years ago."
