I think hcobb's approach works very well. Assign an attribute penalty. Say that a Reptileman is given a penalty of 4 attributes for DX and IQ. Then, a 38 pt. Reptileman may purchase ST as if his total attributes are 38, to purchase DX or IQ he pays as if his total is 42. Etc. Some may be given a bonus to make it easier to get a specific attribute.

The same can done after a particular number is reached. Halflings pay more for ST after they have ST =12. Etc.

Talents can cost double or x1.5 after attributes reach 42, etc.
