Sounds like the old Hero Games model replacing the Dungeons & Dragons model. Back in the day...
In Hero Games (Champions was what they were known for, but they had fantasy and sci-fi versions too) there were no charater levels. Instead you earned points to spend on your character. You still had classes that filtered your options, but you could negotiate with the GM regarding what made sense for you to learn.
Typical fantasy characters started with around 100 points to spend. Super heroes from the comic-book game started with 250. An evening of gaming might earn you 3-5 points. 1 point got you started on a new skill; 3 points made you pretty good at it. Strength of the game was the freedom to customize your character.
