When I want to play a game with a point system such as this, I load up Everquest. The class in that game with the fewest points (they are called Alternate Advancement points there) has over 11,000 such points to earn to buy everything, thanks to the age of the system and the game. The class with the most has over 16,000 AA points.

Eventually such points become a supplement to leveling, and while leveling from 1 to 105 in EQ (or from 1 to 60 here) is one thing, getting 11k+ AA's on top of that is a much more daunting task. Adding such points to this game will result in getting to a similar place should the game last long enough.
