One of the faults of first edition ForeSight (ForeSight being in general my favourite RPG rules) was that the different pricing schemes for skills and attributes in generation points and in experience points imposed a strong incentive to specialise in generation generalise with experience¹. Some players found low levels of skills so expensive in GPs that they felt compelled to dispense with them in generation, buy them with their first experience award, and suppose that they had always been there.
¹ This was declared to be a feature, not a bug. The only reason I can see is that it was in the documentation.
