Not once did I see a clipping problem. In my opinion, the color tone could have been a little more distinct in places. The same interface as Quake 2, therefore the same comments and score. There are no serious problems with the interface. The ability to fully program the keyboard and mouse to your own preferred settings is excellent as is the 'reset to defaults' option if you really blow it.
Movement is intuitive and accomplishing normal tasks is easy .
It wasn't 'bad, I just have a different taste I guess. As with the Quake2 I really wish they had done something better for the 'jump sound'. Artificial intelligence in this game does not appear to have improved over the original. Enemies still do stupid things, but they still are challenging. The real beauty of Quake 2 and The Reckoning is multiplayer replayability.
