Are there any RPG's that don't use advancement systems?

[Captain Stern]

I don't know if I'm the only one who thinks this but I hate the whole advancement thing that you get with every rpg I've seen.

Example:

Bob Billson lives in a quaint little village a few miles from Baldur's Gate. Bob Billson soon becomes tired of his life in the village and decides to go out adventuring. After a month or two of adventuring Bob Billson decides to return home so his mum can wash his dirty laundry. Bob Billson soon discovers that he's like the arch angel of death compared to everyone else in the village and that he could wipe out the whole village if he wanted!

To me advancement lessens the realism of Role Playing and so it becomes more like a game and less like escapism.

So does any one know if there are any RPG's out there that don't have an advancement system or perhaps then a more realistic advancement system?
