so in all honesty, is this game worth getting? i am horrible at racing games but i still love to play them. NFSU1 was cool, but i had to use gameshark to unlock stuff (since i suck at these types of games) and i haven't played NFSU2 yet. Forza looks good and i love my xbox, but recently my ps2 has been neglected for halo2. honest opinions please.
