ASk HN: Open Ended Playing Card "Game"?

I never heard of roll20 before, but it looks really cool. I'll have to give it a spin.

As for designing components and actions, maybe open ended to too far of a stretch and instead maybe have a "subset" of open ended. As in not cumbersome enough to prevent people from using it, but still open enough to make some creative card games possible.

Tricky, because you need to define the components (hands, face down piles, face up piles, etc.) and the actions that can be done with each of them, and then design ways to handle them all in a UI that isn't overly cumbersome for the specific subset needed to play any given game.

Its a good idea and it is certainly possible, though.

I guess this could be done with http://roll20.net/ but I haven't actually tried playing cards with that software.
