If you could spend a day in any location from a game...

[Curunen]

Guild wars 2 - Divinitys reach

On that note - The Grove would be pretty amazing to experience.

I tend to forget how well crafted the locations are in that game.

Probably not a wise destination but the location that was a most amazing scenario or atmosphere I think was the original Another World. Very simple game, brilliant style though

[Cavallino]

Party Games on the Amiga

 

[RageQuit©]

Definetly Skyrim. I would make it to the sanctuary of Whiterun, then spend all day everyday in The Bannered Mare

 

[ak22]

Super Mario galaxy

Star Wars: The Old Republic online

 

[Subzero85]

Probably black mesa from half life 1, I know it wouldn't be nice being hunted down by marines, black ops and aliens, but that game was my childhood, great fps experience back in the day !!!

 

[Fulax]

Tenpenny Tower from Fallout 3. Spend the day sipping expensive whisky, sniping ghouls from the safety of my balcony, and watching the odd mushroom cloud appear on the horizon. Good times.
