I've got some too:

1. Homeworld 2
2. Diablo 1
3. Interstate 76
4. South Park - The Stick of Truth
5. Company of Heroes Series (except the last one which is schit..... :(((( )
6. Need For Speed - Most Wanted (1st edition)
7. The Settlers 1
8. Tomb Raider (latest)
9. Golden Axe 1
10. Theme Hospital

hey kudos on 9.
:D

The games I've spent the most time on (probably) (in no particular order):

Might and Magic Book 2+
Neverwinter Nights*++
Empire Earth
Rise of Nations
Imperium Galactica 2**
Guild Wars++
Thief: Deadly Shadows^^
Legend of Zelda^^
Star Wars: Empire At War%
Lords of the Realm 2

+: Likely 500+ hours
++: Definitely 500+ hours
*: Life replacement for a few months of my life
**: Significant addiction caused me to throw away all of my games and not play any for maybe 6 months to detox
^^: Only games I've played through at least 4 times, beginning to end, that wasn't a strategy game
%: Don't believe my Steam profile. I've played it a WHOLE lot more than that from a non-Steam install (Steam only shows 25 hours).

mostly retro....

1. Silent Hill (PS)
2. Resident Evil 2 (PS)
3. Star Control 2 (3DO)
4. Fallout 2 (PC)
5. Terranigma (SNES)
6. Fantasy World Dizzy (Spectrum)
7. Secret of Mana (SNES)
8. Diablo (PC)
9. Resident Evil (PS)
10. Roller Coaster (Spectrum)

Wow. This is going to be hard. This list is not necessarily synonymous with my favorites list.
(In no particular order.)
1. Rise of Nations
2. The Legend of Zelda: A Link to the Past (In tough competition from Wind Waker)
3. Sou Calibur II (Really tough call between this and the first one)
4. Age of Empires II
5. Yoshi's Island
6. Super Mario Bros. 3
7. Super Smash Bros. Melee
8. Medieval II
9. Pac Man (Arcade)
10. Wolfenstein 3d

For being my favorite genre, I just realized I didn't put any RPGs on there... Maybe a favorites list would see them.

This is obviously very prone to subjectivity, but here it goes (actually in no particular order):

- The Legend of Zelda: A Link To The Past
- Terranigma
- Grim Fandango
- Silent Hill 2
- Super Mario Bros. 3
- Broken Sword: The Shadow of The Templars
- Loom
- Psychonauts
- Legacy of Kain: Soul Reaver
- Gabriel Knight: Sins of The Fathers

And an honorable mention to my dear Nox, which I love to death but don't think is good enough to make it to any "10 BEST Games of All Time" list, unfortunately. It's on my personal one, though.


[EDIT] I had forgotten my usual "link every mentioned game to their GOG or Moby Games page" practice.

Fine:
1) Planet of Death: Gold
2) Pokemon Emerald
3) Tekken 3
4) DOOM and Blood (Couldn't decide- My two favorite classic FPS games.)
5) Fallout 2
6) Roller Coaster Tycoon 2
7) Arkham City
8) Jedi Knight 2: Jedi Outcast
9) Gran Turismo
10) Commander Keen
Very opinionated, obviously.

Oh my gosh, the memories! XD Dad (a doctor) and I would go down to the food court every day during lunch and play Golden Axe in the arcade until it was time to go back to work! At first we were plugging in the quarters, but we soon got so good at the game that it took just a quarter each to keep us entertained through the lunch hour! lol~

This is obviously not subjective at all, but rather indisputable gospel:
1) Hoshigami: Ruining Blue Earth (PSX)
2) Vagrant Story (PSX)
3) SSI Gold Box Series (PC)
4) Fallout Tactics (PC)
5) Prince of Persia Series (PC)
6) Etherlords 2 (PC)
7) Parasite Eve Series (PSX)
8) King's Bounty: The Legend (PC)
9) Final Fantasy Tactics (PSX)
10) Commandos (PC)

Oh I wish I could've played it on the arcade, but I only had the dos version. Always played as the dwarf :)

Oh my gosh, it was SO fun, not only because we rocked at the game, but the atmosphere and the bonding experience with Dad -- great memories!

I can only imagine :)

That's a necro, alright.

This was hard to put together cause I just know that as soon as I post, I'll think of another game to maybe replace one on the list.
In no particular order:

Post Mortem (the first of the Still Life series)
Still Life-1 and Still Life-2
Gabriel Knight Sins of the Fathers
Gabriel Knoght The Beast Within
Black Mirror-1
Black Mirror-2
Penumbra Overture
Penumbra Black Plague
Miasmata
The Last Express

Ooops, forgot to add Metro 2033. In order to keep it at 10, I'll combine the two Black Mirror games.

Okay...If I combine the Penumbras, I can add Tex Murphy's Pandora Directive.
And if I combine the Gabriel Knight's, I can add Morrowind.
And I'm adding Bioshock Inifinite, so I need to combine the Post Mortem/Still Life series.
That makes 10 !! :D LOL

In no particular order:

Arcanum
Deus Ex
Fallout 2
Krash Karts (I may have this title wrong, but I played a kart racing game that was awesome)
Oblivion
Legend of Zelda
Nethack
Dwarf Fortress
Civilization V (with Gods and Brave New World)
VTMB

yeah, this list sucks. it's so wrong. you need like 50 games

The only list that counts is the list of games I play and then play again and then play again years later.
