i love the people who try to diss on this. like the guy who said he would rather buy a new game that the same game with a new campaign and forge. because if they would add this it is ALL they would work on. definitely. no. and when he said "oh, im being stupid, ur the one who wants to stick a double block up the arse of the warthog", i loved how he completely underminded the fact that putting a turret on a warthog could improve gameplay if used correctly, which is all that we are asking. right now, i doubt it willl happen, but i wish it did.
i think this idea could be fun, but like steve said, it kind of defeats the variations of vehicles. i think all of the 7 year old children will destroy the concept of a vehicle with this, but, when used responsibly, this could cause great and fun games. (im thinking merging a radio antenna into the side of a 'hog and having epic jousting battles!)
