Dude, I was 9 or 10 when I got the game. Don't think CIA will come and hunt you down. OK, they will, but hey, who hasn't been chased by CIA these days?
BTW, you said you owned Counter-Strike. Try downloading the editor for that, belive it's like Valve Hammer Editor or whatever. Anyway, since am OFP addon is a direct game modification that'll include a totally new unit directly in-game, VHE will let you get an easy start, learning what textures and stuff are, and let you give some advice on simpler modelling. Just an advice, but it's gonna be much easier getting into OFP addon editing if you've had some other, easier, experience.
