Would the system benefit from ability scores being capped at a maximum according to their level of race?
Normal: No racial bonus to an ability score may be higher than +2.
Advanced: No racial bonus to an ability score may be higher than +4.
Monstrous: No limits.
I think that might be reasonable. Personally, I would be tempted to rate every ability that costs 4 or more RP as Advanced or Monstrous (which would include Advanced Strength/Intelligence/etc.). Maybe it would be worth getting some clarification on what the Advanced and Monstrous categories are supposed to represent.
I saw the ability that allows you to keep boosting ability scores every time you add it.
I think that each size category should have a physical score limitation unless you buy another RP ability to exceed the cap. The ability that allows you to exceed the cap should be expensive though.
As for how to limit mental scores I don't know.
I don't want a hard cap as the OP suggest since I think some GM's will use this to create homebrew races(monsters) as well.
I might push the limits up by +2 (don't want to leave goblins out in the cold), but otherwise this seems like a very good idea.

I agree +4 for standard. +6 for advanced and any for monstrous.
