Mercenaries 2 ... Is it right for me?

2005...Mercenaries becomes a breakout success...2008...Mercenaries 2:World in Flames becomes my obsession. I think I should BUY this game because it is one the sandbox games I've been waiting for.This game has amazed me in many ways. Ragdoll PHYSICS, air strikes,RPG's,and many more. I haven't gone crazy for this game, which is miracle for my mom. But I still want to get this game.Well,what do u think? Should I get this game or not? PLEASE COMMENT
