I've been playing Mercenaries 2 pretty much non-stop since it came out on Sunday.  Very convenient to come out on a three-day weekend like that!  If GTA IV hadn't come out, this would easily be the best open-world game this generation, and in some ways I like it more than GTA.  GTA is more polished, but Mercs 2 isn't afraid to just plain be fun. 

I play a lot of games but it's relatively rare that I get "gamelock" on any one particular game anymore, and can play nothing else.  Mercs 2 accomplished that easily.  My brief foray into co-op was a lot of fun, but I was too eager to unlock more in single player.  Now that I know my way around the game a bit more, I think co-op may be the gift that keeps on giving.

It certainly has it's share of flaws -- if you are looking for a game where you will never see a weird physics problem or movement glitch, look elsewhere.  Audio clips are very repetitive, and sometimes things just kind of break.  But those little bad moments are, for me at least, completely overshadowed by the Pure Awesome that suffuses the rest of the experience.

Now if you'll excuse me, I need to get back to chasing down a few more HVTs for the PLAV.
