I didn't count Interstate 'cause I meant the big WW2 mods, my bad.
And @mrhow:
I absolutely understand that and it's an absolutely sufficient reason. Though I advise you to not pinpoint only on creating cool stuff, but to get direct contact to the industry. Go apply for some practical months in a studio, there are plenty studios looking for new faces (especially cause they don't have to pay that much for them...
), but it will grant you vital first connections.
I once applied at Ubisoft for 6 months of cheap paid work as a game design noob (500€ per month...not much, but it suffices) and it was a really cool time mostly and I'm still in contact with some of the guys there and others I got to know by working there. But game design never really was my first aspiration (though I'd definetly love to work there!) so I returned to studying at good ol' university the following semester
and like to keep a small line into the "industry" if I decide to really go working there.
Oh...I just saw your profile and saw you are quite young
. Okay, then forget about what I said for now and go finish school first
