Making said character sleep to level is imposing a small bit of roleplay on the character. Roleplayers like it, I understand that. Roleplay to your heart's content, I don't care. I'm just saying in a game where you're supposed to "learn by doing" having to sleep when you're ready to level seems completely backwards.
I play TES for the exploration and combat, could care less about RP. I'm just asking for a system that doesn't get in my way and force me to do things I really don't want to do every couple hours. Would love to play without sleeping or waiting for once...
Then might I suggest you don't play a RPG if you don't want to have 'a small bit' of roleplay. Perhaps Just Cause 2 will be better for your combat/exploration needs.
As for me.
1. Remove the level up indicator.
2. Have the day's fatigue cause me to need to sleep.
3. Give me a suprise when I wake if I can level.
(hardcoe
4. Cause my skills not to raise after the 4th or 5th day of no sleeping.
At that point I'll be a walking zombie fighting without technique, and couln't remember my name let alone any skills I learned.)
