GTA IV (360) - [Played it on PC, enjoyed it immensely, bought the expansions for 360 then the original.] Hell yes it was worth it, love this game.
Saints Row (360) - Yes, but partly no. I played SR2 (PC) first, enjoyed that greatly and wanted to know a little bit of the backstory plus I was having problems since it was having a minor disagreement with Windows 7, by which I mean that it had 3 states it would alternate between, crashing instantly on launch, crashing during title screens, crashing once into the game. So I hunted down the first one. It's good fun but the amount of polish it lacks over it's brother is harsh. So a note to anyone who is thinking of playing SR2 without playing SR, do yourself a favour and do SR first. You'll enjoy the upgrades they make
Medal of Honor (PC) - Yes and mostly No. I enjoyed it thoroughly while it was going. I imagine this is what it must be like to be on the end of pre-mature ejaculation. Just starts getting good then it's all over and your left wondering what happened and whether you need to see the doctor. [Read this as I finished the campaign in 5 hours on hard, and I don't play multi player. That and the lighting is brilliant but absolutely brutal on the eyes.
