that would be the stuff of dreams

they should have all timelines

Old republic

fall of the republic

rise of new republic

new republic

jedi purge

force unleashed

rise of the empire

shadows of the empire

fall of the empire

luke builds a new republic

Fire Emblem: Radiant Dawn.

Though I like the Star Wars/Mass Effect idea.

And I think Red Dead Redemption would make it for me too.

That is a big distance to cover and the game would be covering over 4000 years it would take you an eternity to cover all of that stuff it would take longer then Duke Nukem to create. And that is  a big gap for players to cross have people form the old republic with clone wars.

Secret of the monkey island or Civilization

i know thats why i called it the stuff of dreams

i am ready to wait but i would like to play that thing before i die

i can stay in a star wars world for a long time as its my favourite movie series

Call of Uncharted

Total War series. Probably Empire.

The amount of hours that game takes from you is just crazy!

i change it would have to be LBP2 

then you create the games you want 

Unless you are like me and have caught all the pokemon.

For me: StarCraft or GTA: San Andreas/SAMP with access to unlimited mods.

Well I could cheat and name more than one, but anyway I'm going with:

SimCity 4
