3. GTA San Andreas

4. World Of Warcraft

5. Far Cry

6. Little Big Adventure

7. Dishonored

8. Age of Mythology

Top 20 would be easier, but here goes:

1) Morrowind

2) Gothic 1

3) Deus Ex 1

4) Thief 2

5) Thief 1

6) Gothic 2

7) Age Of Empires 2

8) The Longest Journey

9) Flight Simulator X

10) Anno 1404

If I did top 20, it would be too easy. With top 10, you have to really decide which ones fall into your favorites list, which is definitely not easy I'll admit lol.

Hard to determine a top ten of all time, as I find my all time favorite games tend to change a lot depending on how hard the nostalgia strikes with a certain game during a certain time. However, there are always a select few I always cherish. This is somewhat not in any order.

1. Bioshock

2. Fallout New Vegas

3. Red Dead Redemption

4. Fallout 2

5. Deus Ex

6. Deus Ex: Human Revolution

7. System Shock 2

8. Dark Souls

9. Metroid Fusion

10. Halo 3

The Witcher 2 and a Mass Effect game were close to falling in there. But it's nice to see many have already mentioned Deus Ex so far.

EDIT: See, I just switched out The Witcher 2 with Metroid. Changes a lot.

Totally expected imo, a cult game. I predict a lot of Morrowind nomination too.

I do not know if I can come up with 10, but here the ones I think were rather awesome when I play(ed) them:

01) Master of Magic

02) SW:KotOR I

03) Morrowind

04) Fallout 3

05) Madden NFL

06) Ticket to Ride

07) Empire Builder

08) SW:KotOR II

09) SW: Jedi Academy

10) Arx Fatalis

Wow! I found ten

Hmm, a bit rough, but at least it's not top 5, that always svcks having to figure out which games make the cut and which don't.

In no particular order:

1. Secret of Mana

2. Earthbound

3. Heroes of Might and Magic III

4. Daggerfall

5. Neverwinter Nights

6. Final Fantasy VI(III in the states)

7. Final Fantasy XI

8. Rune Factory

9. Disgaea(any of them, I rate all of them roughly the same)

10. Blue Dragon(simply because it's the only RPG I've ever gotten my wife to play)

I know there are a few sequels on my list, but they were good games IMO, back when actually improving the design and expanding on a game mattered. The two KotOR's narrowally missed this list, but the First One was too slow starting, and the second one took too long to get an actual Lightsaber. I was debating to put some N64 games on here, but I really couldn't think of any that would make the All-Time list, but some would definitly get the Honorable Mentions. I would have put one of the Mass Effect games on here, but they all had something that held them back form the All-Time list.

Hard to choose, but in no particular order, here goes:

Morrowind
Bauldurs gate 2
fallout new vegas
Mount & blade warband
Star wars Knights of the old republic 2
fallout 2
arcanum
Civilization 4
x com enemy within (with longwar mod)
star wars Battlefront 2

Thought I posted mine yesterday, but I guess I didn't...anyway:

1. Yoshi's Island

2. Banjo-Tooie

3. Pokemon Ruby

4. Fallout: New Vegas

5. Morrowind

6. Oblivion

7. Skyrim

8. Fallout 3

9. GTA: San Andreas

10. TF2

Again, in no particular order -

Fallout: New Vegas

Fallout 2

Fallout 3

Civilization IV (with the Beyond the Sword expansion)

Doom II

Halo 2

Borderlands 2

Skyrim

Oblivion

Command & Conquer - Red Alert 2
Halo - Combat Evolved
Rainbow Six - Rogue Spear

Oblivion

Fallout 3

Ego Draconis

Divinity Original Sin

Dragon Age Inquisition

Bioshock Infinite

Morrowind

Dragon Age Oranges

New Vegas

Half Life 2

Wondering if I should replace HL2 with Mass Effect. Hmm. And Machinarium belongs in there somewhere for being cute. And Sims 3 because, well, Sims. And stuff.

Sigh, I thought it'd be hard thinking of 10, but like others, it's turned out to be harder fitting my favourites into just 10 spaces. I think TES, Fallout, Divinity and Dragon Age have an unfair advantage by getting two nominations each.

1. Civilization 2

2. Ultima 6

3. DaggerFall

4. Oblivion

5. Skyrim

6. Final Fantasy 7

7. Rome Total War 1

8. Age of Empires 2
