These occupied a major place in my imaginative landscape as well.

I know nothing about the TTA RPG itself, but Talislanta 4E (and 5E) are freely available on talislanta.com.  4E is fairly straightforward.  It’s not terribly exciting but not awful, light to medium in complexity depending on your criteria for such things, makes heavy use of “archetypes” for character creation, which are sort of halfway between proto-playbooks and pre-gen characters.  It’s not a selling point for me, but its also not a “oh lord, what were they thinking” thing either, that they used that system.
