I understand that neither of these games have anything in common but, I can't decide which one to buy. I love both COD MW and Tools of Destruction. I am anticipating both sequals. So, which one will be a better buy? I think COD MW 2 may be the one to choose because of the multiplayer, but the storyline might not be all that. I do love the creativity of Ratchet and prefer Sony exclusives. Anyone having a dilema like this one?     

Get ratchet

I know buy them both

That's a tough one.

i don't understand that.

you should get MF2 if you prefer online over single-player, if not then definitely Ratchet.

Get ratchet.

I'm playing it now and it's awesome!!!

I think he means if MW2 was a Sony exclusive, it would look more appealing to him and put it on even standing with Ratchet and Clank.

Get MW2, you'll get so much more replay value and fun with friends.

Well MW2 won't cut the price for years, so get it first and R&C some months later.

I'd buy Cod MW2. I too love the ratchet series. But I also have cod4 and waw and while waw had a pretty rubbish SP, its the MP where they both thrive. Ratchet seems to be getting roughly the same or even less positive reviews from most game reviewers due to the fact it doesnt do anything new. MW2 I cannot comment on atm due to its lack of reviews, but judging by number 4 it will be a scorcher, 94 metacritic at least.
So in short, buy MW2!
