I decided to rent it out. Previous titles I absolutely hated. The only one I liked was CoD4 but just barely. In any event I'd say buy. Why? Because to me I enjoyed it and while I see that it's the same old same old. I felt they put more effort into trying to make this a good game as possible.
And this is coming from someone that placed MW2 as the worst game ever played.
I'm not interested on online multiplayer, so I rented it from the Redbox machine for $2 yesterday. Awesome campaign and the villain is great. Plus, you get to slap around Manuel Noriega a lot. Beat it in 5-6 hours, then returned it. Great entertainment for $2.
My name's Reggie. I'm about kickin' ass. I'm about takin' names. And we're about makin' games.
