Got my Rising Sun last week, unwrapped and tried a run through (solo) of the rules with 3 clans.
The system plays much smoother than Blood Rage. Almost eliminates luck (you just need to randomly assign clans to players) and everything else is strategy, bluff and your negotiation skills.
That said, the last 2 elements might not appeal to everyone. I’m waiting for this weekend when I will be playing a full on 3-4 player game (depending who shows up).
