I've seen people almost come to blows over the individual titles in the series. Do you have any favorites and or any that you think weren't that great?

1. Heroes of Might and Magic Saga (H3 being the best)
2. Final Fantasy Saga (only from I to X)
3. Crash Team Racing
4. Monkey Island Saga
5. Smash Bros Saga

1-Heroes of M&M6
2-Balder's Gate
3-Neverwinter Nights
4-The Witcher
5-Anno 1404 Venice

Not enough Mario three on these lists folks.

Yes, I love CTR too! So many good times!!
And, yes, I love Skyrim and Daggerfall best too! :D :D :D

1) Fallout 2/New Vegas
2) Pokemon Emerald
3) POD Gold
4) Skyrim
5)Terraria

1. UFO: Enemy Unknown (aka X-COM: UFO Defense)

2. The Secret of Monkey Island

3. Little Big Adventure

4. No One Lives Forever

5. Uh...uhm....can't decide, impossibru!!

1 X-men Arcade
2 Turtles in Time
3 Star Wars Kotor 1
4 Medal of Honor [1999]
5 Indiana Jones and the Fate of Atlantis.

Most definitely. 1 & 2 together make the whole story. Sam Lake writes in the same film noir style, continuing where the first one left off, taking you through a comic and tragic emotional wringer that resolves in a classic denouement, tying up all the loose ends. But, the gameplay, the gun play and the level design leave you wanting more.

I often neglect my backlog because I'd rather take an hour to replay my favorite levels. But this is not tragic. :)

1) Mega Man Legends
2) Super Mario 64
3) Toonstruck
4) Threads of Fate
5) Wolfenstein 3D/Spear of Destiny

I don't like multiplayer, even when it's with people I like.

Arcanum
Deus Ex
Oblivion
Planescape: Torment
Fallout 2

runner ups:
Civ IV
Doom II
Dragon Age: Origins
Skyrim
Fallout: New Vegas
Civ V

As you can see, i like really big games. The list is pretty much total play time.

Morrowind
Fallout
Deus Ex
Thief 2
Sam & Max Hit the Road

Those five games build pretty much the entire foundation of my gaming hobby and what I still enjoy today.

HI!

1. Half Life, all of it, specially Opposing Force and 2.
2. Age of empires 1 and 2, plus Steam HD version
3. Commandos series, BTEL + BTCOD + 2 + 3

5. Hitman, all the saga

I am not a multyplayer person, i do preffer a good single player history.

Off the top of my head...
