The gun jamming should not be random, it should occur based on the length of time the trigger is pulled. There are several older games that used this feature. As long as you held the trigger, the gun temperature would rise. If it reached red-line, the guns would jam and you would have to wait a few seconds before you could fire them again. It's a simple thing, avoids having guns permanantly jammed for the entire flight and should satisfy both sides...
1. Realism guys: It will reduce the spray and pray
2. Gamer guys: This feture I described is mostly from arcade games: Cobra Command, Sky Hawk, etc.
