Finding myself a bit light on time today, is tarted looking again at the ioquake3 engine with an interest in playing around with it. Of course, there is nothing better then a real world example - I tested Urban Terror and OpenArena, two games based on ioquake3 and Quake III: Arena game play. Urban Terror applies modern weapons and equipments but beyond that is not really a realism game IMHO. OpenArena on the other hand, sticks close to the core—it is as Quake like as the game play lol.
OpenArena is addictive and you can just feel your brain cells rot away as you engage in the carnage! The game is fairly simple and straight forward, you spawn, you run around, you blow people apart (gibs all over), oh yeah, and there are power ups here and there. Really, there isn't much more to say about it then that, other then it is strangely enjoyable; no wonder the Quake franchise has made millions.
