I actually thought of doing a similair thread, but it never happened.

I think it's a great idea. I would especially like, not only leveling up, but more of stats. That would increase the replay value over ten times, people would still play their old file to reach all the stats to their fullest extent, and it would also help to create harder extra quests with newer and more difficult enemies, just for the fun of it. To see if you are up to defeating it. If not, go practice some stats you are lacking, then go back.

The thing though, is that most games having such stats as agility and strenght, we never really see it increase more than just on paper if you get my meaning. They say "agility", but it raises more like that enemies cannot dodge your attacks as easily. That is boring. It would be more fun if "agility" or "speed" would actually affect the way you ran. So if you had max in speed, you ran fast as hell.
