Tobold has reworked his MetaLevels concept, and posted it up on Grimwell. I like the way that man thinks.

All level-based games have a maximum level, for example currently 60 in World of Warcraft. While you are below this level cap, you have two choices on how to increase your meta-level: You can either just increase your character level, or try to get better equipment and increase your meta-level over your character level. The problem with the latter solution is that it gets exponentially harder the bigger the difference between your meta-level and character level becomes. As soon as you reach the level cap, improving your equipment is the only way left to you to advance your character.
