Bought gears of war 2...thinking of exchanging it for uncharted 2 should i?

If you don't like Gears 2: Go ahead, trade it in.

If you do like Gears 2: Finish it, play it till you're bored, maybe buy Uncharted 2 later, even if you don't want to trade it in at all.

Uncharted 2 is definitely worth owning but there's no need to trade in a game you like just to buy it...
