The RPG is not even complete.
Also, thoughts on King of Dragon Pass? It's not a standard RPG, but worth considering, and very polished.
I love KoDP, but definitely wouldn't call it a masterpiece (if being a masterpiece requires that the game be near-flawless, as the OP seems to think). For one thing, as far as I can tell, there is really only one viable way to play the game and win: be crazy generous all the time, don't pillage too often, and don't ever piss off the non-human enemies (e.g. trolls). There are other issues, like many of the seemingly-innocuous early-game decisions making the game completely impossible later on (e.g. your initial choice of an ancestral enemy), and it being kinda random whether you succeed at hero quests. Still, despite this stuff, it's a great game.
WRONG!
There is a way to play rich guy, like worship the god of artisan, concentrate on the artisan portion of population, open up trade route etc... In my run it's viable to win second, not Kingship, because the chief was too old. It's a strange and very different way from other plays.
There is also a way expand a clan as big as possible. And the way it ism to raid EVERYONE touching our border. I did it. It's hard because we got retalitation raids every time. It's good because you can use Earthblood ritual thus get rich crop every year. This is also quite different.
Of course, there's also the normal win way everybody can play.
