I've still having fun with it. Of course, we don't play it every day, so the total number of games hasn't been as high as the OP yet. But there's definitely strategy involved, the way we play.
First off, we do have one house-rule - any kind of card can be traded, and you can make complex trades/deals like helping in a fight now for a better trade deal next turn plus not being the target of a particular curse. Secondly, we usually start backstabbing/hindering a lot earlier on than level 9. Especially if anyone assists against a monster with a nasty consequence, that's the chance to screw two people at once.
So the result is, if we're in the mood for that, lots of alliances, deals, and backstabbing. The cards you get may be random, but what you bluff people to think you have isn't.
