I've played Morrowind:
Er, the highest I had was Lilim, who was a Thief as well as an Assassin for the Morag Tong. About level 25ish, and she had finished almost all of the Thieves Guild quests, and did a few Morag Tong quests, as well as a few sub-quests... However, she only did, what, 1% of the Main Quest?
My other character Celia, being a Healer Mage person, took a long time just to level to level 3! (I'm horrible with Magic in this game!)
I've played Arena:
In Arena, I'm still in that first dungeon and only at level 4 with Celia the Healer, and only Level 2 with Gabel the Ohmes Ranger. :ashamed:
