So, apparently I missed a lot in the two years I didn't visit here (particularly an entire ICE Awards where my game was a finalist!).
Now that I'm back, I have updated the rules to Plutonian Poker (finally), available here.
I applied the changes suggested by Bryan and Ryan, and after playtesting them I think they greatly streamline the game- Thanks very much to both of you for the feedback, and I apologize for the delay between the advice and its implementation.
I also added a new optional rule concerning turn order; me and a friend lifted the idea from Catan's setup phase after learning it recently. I think it adds a decent twist, but in larger games it would become cumbersome, and I haven't used it many times so it may not have a lot of staying power.
I was also considering adding a new hand or two; Firstly, an equivalent to the flush which is fiendishly difficult to acquire, lacks partial goals, but has a high-point payoff and noticeable bragging rights if completed. Secondly, another "small" hand that would give 2 and 3 player games more options. Nothing has come to mind while brainstorming, however, so any suggestions about that would be appreciated.
Thanks for reading
This looks like a good game. A possible variant that occurs to me is turnless play as in Icehouse.
Good job. We've played this many times (and with groups up to 6 players), so I look forward to using the updated rules.
