1. Half Life 2
hands down for best innovation, game play, design/artwork and graphics.
Nothing like waking up in the middle of the night to a shadow resembling a “Head Crab”. Yikes!
2. Ghost Recon Advanced Warrior I/II
This is not your typical rush in arcade style fighter, but more of a “take your time/outflank and use and develop your tactical skills.
3. Call Of Duty 1-4;
Excellent graphics and gameplay but at times feels too rushed. COD 2 and 4 is my fav.
4. FarCry and Crysis:
Just stunning and overall enjoyable never boring gameplay.
I’ve got more but want to hear from you folks.
