How can I pick one favorite game????
Psychonauts (gametap) great game!
GTA San Adreas
Empire Earth....like Rise of Nations etc etc but this has from throwing rocks up to tech robots.
Mafia (on gametap) Slower paced, you can't just speed and the police not care but if you can handle the realism it is a true great!
STALKER (gametap) I haven't played any other shooter games I like (Wish I could find one like STALKER)
Second Sight (gametap)
Sid Meiers Pirates! (gametap)
Indigo Prophecy wow!
Fable I love the concept of the character actually growing in a rpg..all rpgs with a story where you start as a kid should "show" the kid evolving in more ways then clothes.
All those games are sweet!

I'll try to make a top 5:

1. Metal Gear Solid
2. Metal Gear Solid 3
3. Metal Gear Solid 2
4. Ratchet and Clank: Up Your Arsenal
5. Team Fortress 2

Either that or:

1. HEYLO 3
2. HEYLO 2
3. HEYLO 1
4. HEYLO WARZ
5. HEYLO ODST EVEN THOUGH ITS NOT OUT YET
