If you could live in any video game world...

Vampire the Masquerade - Bloodlines. Best world to live in ever.

Dead or Alive Xtreme 2

Space Quest lol

Skyloft from Skyward Sword.

beeing someone augmented like in deus ex:HR will be awesome :D

Silent Hill :D

Alternatively: Scribblenauts, with the weird book thingy that is.

Kyrandia. Colorful and fun. There is magic, living and talking trees, bigfoot in a Hefner jacket, you can fly dragons, create flying shoes, gamble with a octopus and walk on the rainbow into space...amongst other things. A childhood dream come true ^^ (Except for bitter, mad powerful jesters, disembodied body parts, etc.).

without a second of question or reservation i would go to the land of the Elder Scrolls, probably take up personal residence in Caldera
nice quiet city with a good fence, sort of central to the more bustling parts of Vaardenfell, and not terribly far from my summer home in Solthseim, with the occasional trip to the Colosseum in Imperial City

Additionally +1 for starting a topic that is actually interesting

Just cause 2 or far cry 3.

Cant explain why,i dont see any reason to not agree with me.

Final Fantasy VIII :) I always loved the idea of magical mercenary academies :D

Animal Crossing. Where else can I get a job shaking trees?

I'm both amazed and slightly disappointed that Minecraft only has one mention in this thread.

Zeno Clash. Or FLY'N. Or CreaVures.

Dayz. I WANT TO RUN WITH THE ZOMBIES

Minecraft.

I've always wanted to punch trees without feeling pain, fall far down into a pool of water without getting hurt, do stuff that can be done only in Minecraft, etc.

I would love to live in Tamriel. And I would visit the sanctuary of The Nine every morning and pray for the blessings of Kynareth. (This makes me miss the old Elder Scrolls games so much. And now... just look around... I'm tierd of proving to stupid, ignorant gamers, that Skyrim is not a world, but a simple Province. )

The Godfather -

Mass Effect. There is nothing more magnificent than Mass Relay

Overlord

Maplestory

Was nearly close to say in battlefield 3, but just in a server plenty of noobs :)
But no, maybe would be better on portal/portal 2 hahaha

Leisure Suit Larry
