I played ninja gaiden for about 10 mins, and got sick of it. Brainless button masher. Very frustrating game with a really pathetic camera that's always in the wrong spot.
COD, and MOH are better on the PC....oh about 10 times better. But Medal of Honor Rising Sun is the better from what I have played. But, never gave COD much of a chance, it just plays so bad next to the pc one I got mad with it.
Burnout 3 is something you should check out. Totally unique race car game. Burnout 2 as well really, but 3 is much much better
Dead or Alive 3, and the new one called DOA Ulitmate is a must have for friends visiting the house. I think that game gets played the most by company. Don't forget Mortal Kombat Deceptions as well, but to me DOA is much more fun.
Don't' forget Halo1, which u should play first before 2 so you know wtf is going on. If you play #2 first, I don't think you'll have enough patience to get through 1 because you'll miss certain weapons and vehicles and s***.
Some like the Prince Of Persia game, and the new one called is warrior within. Only seen the first few minutes so far, but it looks pretty. Be aware though that POP is a bit of a platform "jumping" game with puzzles. not everyones' cup of tea.
Fable has gotten good reviews for sure
007 Everything or Nothing would be at the TOP of my list. One of the best all around games of the year imho.
Chronicles of Riddict, believe it or not is actually really good.
I'm not a big dirt bike game fan, but I fell in love with MX unleashed. Best dirt bike game EVAR.
That'll get you started. I know I am missing one for sure.
