Good news:
I think I've got the entire framework for the MR card game Sven suggested ready. Card design, gameplay, rules, several cards, card systems, gacha systems, etc. 

Bad news:
David's gonna have a fuck of a time programming this, especially if we want to be able to play against each other. 
I'm gonna need so much fucking information from everyone that it could take years to finish. 
It'll probably be on David to build the cards themselves out of the assets I give him, since he has photoshop and I don't. 
I have no idea if it would be better to build the entire thing up to current time and have it be V.1.0 and then update as shit happens IC, or if it should be built to V.0.5 and just have everything as updates from there. That would give us more bug info for David and would increase everyone's ability to progress at speed but would end up with months of downtime between updates due to the huge amount of content per update.
Whether this gets built or not is basically on David's shoulder.
