I've had started to write out monster stat blocks for six colors of dragons in three age categories each, because in D&D 3rd ed. you have to assemble any dragon from several tables instead of getting a stat block like for any other creature.
The only thing still missing was distributing skill points. And I'm definitely going to need a spreadsheet for this.
An old silver dragon has 372 skill points to distribute. (A number I had to calculate myself.)
3rd ed. dragon stats suck!!!
