My 'most' main character would still be Adam on PS3, he's level 40 and his save file is now 12 mb.

Ive gotten mine to 12mb as well. Also on PS3. Just started a new game and am going to try the janitor method.

My very first character had a save file of 22MB.

I haven't got a main character. My current character's save file size is 7MB. I have played as her for 50 hours.
The largest save file I have had for an old character was 16MB

Problem is, I have no characters.

Bugs took Hrafna away from me (again) and I feel discouraged to start over (again).

And I don't feel like I got fresh ideas.

Try a different race and be a criminal. Maybe an Orc thief or ass-ass-in.

My current character's save file is 9,312 kb, after about 95 hours of gameplay (PC).

My main character file is 17,041 kb and is level 72.

Lvl 80 17Mb 200+hours /all dlc PS3

M'aiq has 1GB on his main character, whom is a Khajiit and named M'aiq the Truthful.

Level 81 24Mb on the Xbox 360, he has done just about everything, with all the DLC and been every where.

Same character at level 83 and with a fair few mods on the PC is 27Mb. He has been leading a double life since he was level 79. Both versions have well over 1500hrs, and he was my first character from Nov 2011.

My longest lasting character finished all the DLC and had 2655 saves & 190 hours. 23MB save file (and there were probably ~200 mods).

... and now at 094.27.55 hours, it's 9,073 lb.

My Current character is at level 52
save file size - 11412 KB

Hours - More than 120+ i guess dont know the exact
