Wait, totally forgot the best game EVER (EVER)
Crossbows and Catapults.... you would put rubber bands on these little launchers and you were SUPPOSED to try and blow each others castles up... well, you could put liek 60 rubber bands on one of these crossbows and the little pucks would reach WARP SPEED and break your brothers leg... good fun
check out how much they're going for now!
