Oblivion
No.
Agreed.
I will be flamed for this,but admit it.Runescape is kind of a sandbox game... no, just noAlso Borderlands? sorta, it's more of a free roam, you don't have unlimited possibilitiesNeed for speed, only the ones with freeroam though... noNot sure about anything else Garry's Mod
fuel is a racing game but has a free roam sandbox type thingthe map in the game broke records for being the biggest map ever
Wurm and minecraft?Also, in runescape you can't just put up a house where ever the forget you want, you get the loading screens and such like the wikipedia article said. Runescape is not a sandbox game, neither is WoW, same goes for most MMO's.
