Ridge Racer 6 is out this week on PAL (Friday 20th), the newest batch of Ridge Racer on USA is region locked

If your into racing stuff then its great (Ive played it for over 32hours so far) has a fantastic online section as well.
Others Id say what I have...
COD2 - Excellent, slightly better graphics over the high end PC version definite buy if you like FPS
Kameo - Not played yet, tried it on demo pod on release day and bought looked lovely (but Im told from friends its short)
Condemed - Very nice FPS, not much replay value but its great, from the FEAR team on PC
Tiger Woods - Above average game because it has more taken out than the Xbox 1 version
Madden - Biggest disapointment for me, 2nd reason I wanted a 360 (PGR3 first) and its had loads taken out over xbox1 including madden commentary
PDZ - Above average in single player, some very good sections but also some ropey ones and shouldnt have taken 5 yrs to make. It has a problem with certain ISPs for online though and mine wouldnt connect to online sessions (although I could start my own), its the only game I have a problem with on live so it went back for Condemed as a faulty purchase (after I had finished the single player).
PGR3 - Yep top game another must buy
DOA4 - (USA region free) - A nice graphical DOA series, still the same though either very weak AI or counter crazy, its good but online theres a few lag problems. I dunno with DOA I just find it too easy single player over VF4 evo and Tekken, but I must admit I only really enjoy VF4 evo out of 3d ones my favs are 2d like Garou MOW, Last Blade and SF2
NFSMW - The suprise for me, I purchased it on a whim on launch day to take back under games 10day return policy (as at the time NBA 2k6 was due out the following week but its put back till Jan 27th now and I was going to swap it for that) but I put it in as my first game and then played nothing else till the following Wednesday (even RR6 was sealed till then). Its just a great fun game.
