Can't believe i didn't mention daggerfall and morrowind. Daggerfall by far was amazing for what my tiny 8 year old brain could fathom. All the quests and the haunted king and orc fortresses, very intimidating and definitely can't forget the titties in the temple.
Morrowind might still be the pen-ultimate open world RPG. Skyrim looks shiny and is fun to play, but lacks the depth that chat dialogue vs. voice acted loops can offer. The world and towns are so small in Skyrim you have to constantly use your disbelief suspend to feel even slightly immersed. Oh this is your capital city? population 50.
Enough Bethesda rants, heres a link to daggerfall unity, enjoy! This is without a doubt, the daggerfall we didn't know we needed, and wish we had as kids!
