Personally i have been playing MMOs ever since EQ released and there was no way back for me...

daggerfall was however the best single player game i ever played and the first true sandbox game, i tried all later elder scrolls games, but they made me realise how important an online community and online competition was for my gaming needs, i dont think i played any of them for more the 100 hours.

I didnt like redguard that much, but was never intoo adventuring games that much.
