maybe you can spend money on better pc equipment? i guess that'd be pointless if you don't really play a whole lot, but you can get some good out of it anyway for when you do play.
a car works too. take your friends to buffalo wild wings if there's one near you. that place is always fun to eat at. take vacations whenever you can (when you have a car) that aren't like super expensive but can provide a good time. i mean there's a whole other part of this world besides the state you live in and the states connected to yours. visit it when you have the free time. i've personally never really travelled anywhere, but i have friends and former friends who have been all over the world and say that it's the greatest time they've ever had.
these might not really be goals per se, but just more or less things you can do that up your life with the money you don't really seem to want to use.
