Ah, now you made me look at my terribly long list of all the games I ever played (and remembered)... It does indeed require some very tough decisions, but here's my attempt:

1. Heroes of Might and Magic (3, then 2, then the rest). Awesome game - played it and all the expansions again and again for years, both campaigns, one-off maps and multiplayer.

2. Civilization 2/3/4 - being close to god just rocks!

3. Guess I have to say the Command & Conquer genre - all the way from Dune 2, through the first C&C, Red Alert to Generals Zero Hour. Along with the warcraft series, this series the bar I reckon. Played them all.

4. Little Big Adventure 2 (1 was save game bugged). Fun, compelling, cute and imaginative - great action/adventure game.

5. North & South - many fond memories of childhood multiplayer games in this one :) - excellent replayability vs. humans.

Runners-up...

6. Ecstatica 1/2- unique and very atmospheric/eerie.

7. World of Warcraft - it did steal roughly 2400 hours of my time...

8. Max Payne 1/2 - with it's original slow-mo bullet time action and nice film noir setting, I'd have to say it's been the most interesting Shoot-em up I can recall.

9. Warhammer - Dark Omen. Perhaps not the greatest game, but as a warhammer player it provided me with the opportunity to see my miniature toy soldiers come to life ;)

10. Far Cry - I personally loved the beautiful graphics and nonlinear 'walkthrough'.

11. Star Wars Pod Racer - Awesome speed!! (with the best racers in late game) - nice graphics and atmosphere too.

... + praise to those forgotten here! (Only naming 5 is clearly not possible;))

Hey, where's my avatar? - I did upload a properly sized picture:P

Ooooh...
There are so many games that are good so its really hard, atleast for me, to rank them. Its a bit like saying, whos the better musician without specifying which genre you're talking about :)

But anywho, here is my list of top 5 games in no specific order:
Civilization 1 & 2 (I really hate 3 & 4)
Any Sierra adventure game (I pretty much love them all the same so its really hard to pick out a specific game)
Tie Fighter (X-wing was good, but Tie Fighter took the game to a whole new level and you got to play as bad guy :)
Half-Life 2, HL2 Episode 1, HL2 Episode 2
Might and Magic 3 (This was the first M&M game I ever played and even tho I liked 4 & 5 they never came near 3 imo)

There are alot more games I could list, but with only mentioning 5 these are the ones that stands out the most.

1.- Warcraft III
2.- Metal Gear Solid
3.- Tales of phantasia.
4.- Final Fantasy IV
5.- System Shock II

Easy :D

Top 5:

1. GTR2
2. rFactor
3. GeneRally (I LOVE this freeware gem)
4. Burnout 3: Takedown
5. Warcraft 3 - FT

honorable mention:

6. TES IV - Oblivion (only if it wouldn't crash >.<)
7. Doom Series
8. NBA Live 08
9. Soldat
10. Heroes of Might and Magic III
11. The Sims

Mine would be: (It'll change every few months)

1. Zombie Panic! Source
2. Loom
3. Garry's Mod 9
4. SourceForts
5. Company of Heroes

I'm not great with these and I have a habit of changing my mind frequently but my top five would look something like this:

1)Shadowrun
2)Super Metroid
3)Super Mario Bros. 3
4)Super Mario Kart
5)Goldeneye

I know, four SNES games but the SNES ruled. :)

Ooooooooh, yeah!

Oh I love so many games...this is going to hard. :oh:

• Fallout
• Civilization 4
• Master of Orion II
• Warcraft III
• Starcraft

Let me add my list that's going to change in 10 days!

1. Ultima VI - IV comes in at a close second, I just liked VI's story more.
2. Ultima IV - It's practically the same as VI except shorter and I didn't like the story as much.
3. Wasteland - Great RPG, if you can get over the bugs and terrible interface (even for its time).
4. Fallout - Because not even its sequel managed to balance everything like this one.
5. Icewind Dale - I don't know about you, but an RPG without a good combat system isn't an RPG in my opinion, and Icewind Dale was awesome.
