I really liked Fluxx when I first played it, but it grew very old very fast. The new spin looks fun - but it still doesn't seem like it'll add more depth to Fluxx.
Have you tried [GAMEID=18333EcoFluxx], or Family Fluxx? Or mixing them together with a normal Fluxx deck to form one big UberFluxx deck?
Or Fluxx Blanxx?
The game of everchanging rules can be everchanging itself.
I'm very much looking forward to Zombie Fluxx, and the new game that's being included in the "3House" booklet.
