You are an idiot, no offense.
Unless you've played the game previously and liked it or you need the game immediately for whatever reason (like tourneys or something), then you always RENT and ask for opinions before buying games. Preordering and all that crap is not worth it most of the time.
If I were you, just trade it in now, get at least half your $$$ back if you're lucky, and go gorge yourself at Subway or something to calm yourself.
