There is a list of a hundred or so things which could have gone into the bot, but when Polge got his new job, he just didn't have time to work on it any more. And you can see that the attraction of working on TWO artificial intelligence projects, one completely unpaid, would be minimal. Let's face it, most of us who are active in the Quake community do it as a method of getting away from our everyday jobs. At higher skill levels, it rarely misses, and shoots at the maximum rate allowed to players, but it never shoots faster than allowed or causes more damage on hits than normal. It also does not move faster than players.
Many people beg to differ.
It's not exactly clear-cut. But once you notice it, it does diminish the enjoyability of playing with Reapers. Well, Polge doesn't have the time or the inclination, but there are many people out there with both who are eager to get their hands on the Reaper and fix it. And with Polge refusing to release the source code, that would appear to be an end to it. The progs.dat that makes up the Reaper patch wasn't scrambled, which makes it possible to decompile the patch, make changes to the source, and recompile the altered version.
