I love MW2 for nostalgic reasons. I admit it had a lot of bugs and very unbalances. Annoying yes. But something about having the most unbalanced gameplay also made it fun. I would still consider it one of my favorite games. MW3 on the other hand. Great desing, and it recieved a lot of praise when it first released. I loved every aspect of it. If i were to chose Id prob pick MW3. It had a better gameplay experience.
