All time favs? hmm this could be tough.
i liked sonic the hedgehog 1 -3,
F.E.A.R 1,
Farcry,
Killzone 1 and 2
Metal Gear Solid 4
Uncharted

I will say Civilization, Need for Speed & Metal Gear Solid .....

1. Skies of Arcadia
2. Grandia
3. King of Fighters XI
4. Bloody Roar 2
5. Rival Schools

Well....

1. Super Mario Galaxy (In the past I don't really like this game, but now? I LOVED it. )
2. Super Smash Bros. Brawl (Obviously.)
3. Itadaki Street DS (A fusion of Monopoly and Mario Party)
4. Elite Beat Agents / Ouendan (Music-based)
5. M.U.G.E.N. (It's very hard to explain this game...)
6. Jump Ultimate Stars (If you are finding any crossover fighting game for the Nintendo DS, check this one. It has "One Piece", "Yu Gi-Oh!", "D-Grayman" and many more. But it's in Japanese version.


There's still tons more though.

1: The Legend of Zelda (haven't played one yet that I didn't like)

2: Mabinogi (used to hate it, sooo much better on broadband)

3: tough call between Halo and Fable

4: Morrowind (great game but I tend to binge it a little)

5: Diablo 2 (classic)

This is just a top 5 off the top of my head, I don't think I'm patient enough to go through all my games and rate them.
