I'm pretty broke right now, but I'd love, absolutely LOVE to own a PS3.
I'd buy god of war 3, devil may cry 4 and C.O.D.
4.Sound system for my Mustang
Completely useless in every way, in fact if I buy a really good one it will more than likely attract the wrong kind of attention, ultimately ending with me getting car jacked at gun point (I love California).
3.Video camera with built in HD
Again completely useless but i'd love to just video tape everything that happens in my life. Not like my life is super interesting but it just be like a fun hobby to document EVERYTHING.
Just in case there are intergalactic invaders that decide they want to swiftly and violently invade this planet with the sole purpose of enslaving the human species, I'd stand in the forefront of earths united fighters ready to put a 9mm slug into anyone trying to take..... OUR FREEDOM!
Also it'd be cool to go to the shooting range.
This is actually legit, I really do want to buy a baby goat and raise it like if it were a dog, maybe raise it along side a puppy.
