COD4
Simply the best FPS ive played on a console can be played like a run and gun fast paced game or as slow and steady as RvS if you switch it to hardcore and with the rigth downloadable content to fill in a couple of minor holes it could be the best game ever. The PC version will get these mods anyway i just hope the 360 version follows suit.
The next 2 are more difficult to pick becasue nothing stands out as far.
Bioshock is probally the best single player game ive played for quite a longtime and has a very good storyline but the game is not without its faults but i think ill still let it into the top 3 purely for being a work of art as much as a game.
Id like to pick forza2 or PGR4 to fill the last stop but both of them wind me up in diffrent ways (timevKudos races in PGR4 that arent races at all they are handbrake tests, overlong races and championships that take 4-5 hrs to complete in Forza2 as well as people simulating whole races to get the money and acheivments)
I find it hard to pick a game for slot3 becasue while there are loads of really really good games they all have something about them to put me off.
GRAW2: Great mp, way too easy SP.
Crackdown: Too short SP and repetative but amazing fun none the less.
Orange box: Portal is a brilliant game is a little short and half of it is training but HL2 is showing its age now and TF2 is just broken on the 360 lastime i tried it the lag was unreal and worse than any other 360 game ive played.
I'm torn so im going to have more of a think.
This is mainly a good thing becasue there have been soooo many above average games for the 360 this last year, my ultra pickyness should not be seen a dig at the games, all the ones ive listed above are brilliant just flawed in some way...
