Won an Xbox360 recently, and thus bought some games for it (as you do).
CoD4: MW: Cost a tenner pre-owned, bargain as far as I'm concerned. Never really did FPSs before (hell, had a bit of a retrofest at a media museum up north on a trip and promptly got shot to bits five times in as many minutes on Goldeneye for the N64), but by God is this a good game. Bit short though and sometimes the camera's a bitch (Crew Expendable when evacuating the ship for example) but still, the thrill you get when you get a clean as a whistle headshot is unreal.
Prototype: Or, as I like to call it "Kill As Many People As You Can In Just About the Most Gruesome Way You Can". Some real freaky **** in this one, but it's still a fun game. Until you get to the Elizabeth Greene boss. Then it gets frustrating, but then the rush you get when you finally kick her arse to Hell? Priceless. Also got this pre-owned (in fact, I have no brand new games, technically), and it too is a bargain, as far as I'm concerned.
Prince of Persia: Not all that far into this (only got it Thursday) but it's alright. Controls are a bit squiffy in as far as the Prince sometimes does the exact opposite of what I want him to do, and the ****ing Warrior is proving a bitch cause I can't hit the fecking X button fast enough, but it's good.
Mirror's Edge: Probably the worst game I have, which is a shame because it has potential, but it's so ****ing frustrating. Controls are shockingly ****, and as for the health system, what health system? 3 shots and you've bloody had it! It is incredibly cool when you get it right though. And having got it for less than a tenner pre-owned (but with a brand new disk - don't ask me how, I don't know), it's worth the money.
Batman: Arkham Asylum GOTY Edition: Oh. My. Gods and Godessess. I'm only 53% through this (which, in 3 days isn't too bad) but wow. Yes, there are some frustrating bits, such as Killer Croc, and yes, it is about as clear as mud what you have to do sometimes, but this game is so good it doesn't matter. How they managed to make one island and what's on it so expansive is beyond me. Can't bloody wait for the sequel. Got it pre-owned for £13 with both sets of glasses as well.
Assassin's Creed: Got this for a fiver. Controls are finikety, and I have no idea about the story since I played the opening bit of the game on as good as mute (it was near midnight, the parents were asleep in the next room). Pretty good game though.
Army of Two: Normally, I wouldn't buy this game (I've heard it's shockingly ****). However, it was the first of many games my friend gave to me on account of his Xbox breaking down for my birthday so I wasn't going to turn him down. It's not bad. Not the best game ever, and I can see why it's been taking most of the stick it's taken, but it's not exactly a contender for Worst Game Ever.
Lost Planet Extreme Edition: Gameplay wise it looks like being Extreme has no effect what so ever, but it's a cool case and has the art book in it (another pass off from my friend, as I believe all of them are from now, he keeps his disks in good nick). Played a bit of it (Batman, Assassin's and Bioshock have been wiping out my days mostly), and it seems pretty cool. Some pretty kick arse weapons at least, always fun to use those.
Bioshock: The metal case edition (what that means beyond it still selling for £54 on Amazon I've no idea). Holy ****. I know what happens (well, I know the phrase "would you kidly" comes into it), but I think that makes it even better when you notice things like that. Besides, Electrocuting a Splicer before bashing it over the head with the Wrench or blasting it with the Pistol or Shotgun? Cool!)
Just Cause: Think GTA on an island somewhere in South America (he says based on the accents and names of places and people). And it's officially sanctioned by the CIA. Not that it stops you from being chased by police. Seems alright, not played it much though.
And, finally, Prey: Seems a good little game so far, not that I'm all that far into it. It does have a track from the Mighty Morphin Power Rangers movie (the one with Ivan Ooze) in the first scene though.
Hmm, I'm thinking Star Wars: The Force Unleashed next, then Assassin's Creed 2 (which was going for a tenner pre-owned in my local Game store)...
