I've heard more about camping than I thought possible. My personnaly thoughts on camping are that it adds to the diversity of the Quake community. Sure I'll admit at times I want to play a camp free game, and I have had such oppurtunities many time. This is a good point, but in Quake you respwan anyway so you can just go and have more fun. Guess he said it all.
Camping is just another strategy of the game.
If all you want to do is camp play Counter-Strike. If letting those people camp is what it takes to get them to play Quake, then I'm all for allowing it. But as I said before, don't let it be all that you do. There's usually better ways to get frags in the long run. I've seen quite a few guys run amok in the maps.
