Oh, and also, when I say random maps, I don't mean for the game to chose a random map from a chosen map rotation list, but a random map from all thousands of maps you might have lurking in your BaseQ3 folder
This way, when you are in the game playing against bots, you could just hit a key or go through a menu to switch to the next random level, which could surprise you by being any map in your Quake3 folder (a map for that game type of course)
