I own and have played a few sessions of BoL: I liked it, but my group didn't really take to the "nebulous" task system, nor the "requires creativity" sorcery system (i.e., no list of spells, just make stuff up and GM adjudicates difficulty on the fly). It's similar to Traveller in that it uses a 2d6 roll high core resolution mechanic (so, easy to pick up), but doesn't break skills down into more than "careers": e.g., an "Assassin" doesn't have an enumerated list of skills, just guidelines for what they'd be good at (disguise, sneaking, poisions, etc.). In our sessions it appeared that the heroes were truly heroic from the beginning, so there was no slow power curve. Easy to port to other genres, too.
