Morrowind: This ES game is 15 years old, but despite beating the main quest and most others, I am still discovering new things in this game.

Oblivion: I traveled the entire game in just a week.

Skyrim: Same as Oblivion, but a bit longer perhaps.

Takeaway: Morrowind was not only the best installment of this series, it is the most explorable and that is why I would rather sacrifice the "Goody", memory hogging, slightly rewarding graphics, for a plethora of MORE rewarding, game content.

Sub comment: I might also mention, I like the leveling in this rendition - Far better than Oblivion(which has too many limits) or Skyrim.

I've always thought Vvardenfell and Solstheim were fascinating places to explore. I've spent more hours than I can count (it must be over 6000 by now) exploring this game. Vvardenfell never fails to intrigue me.
