Morrowind with OpenMW. 
Well that's a lie mostly I've been modding it and done a few test runs to see if everything works. 
It's just so great to be able to get a ship from Ebonheart(on mainland) to go to Anvil in Cyrodil and then come back and take a boat to Karthwasten in Skyrim.

all substories, all directives, all weapons unlocked, all modes open and all the things and or lore watched. I'm sad that it's over though now I need to find another 'trash' game to play
