Re mental card games; I never did complete the design for my imaginary-card game. Basic concept was to start with something like poker. Make up your own hand and write it down. Reveal hands. Any two hands which share a card are invalid; after that, score normally. (Or perhaps just lose the conflicting cards, then score what’s left normally.) The goal, of course, is to guess the other players’ strategy and style well enough to come up with a hand that scores better but avoids their probable hands… or perhaps tries to sabotage someone’s hand, depending on how the game is going.
Needs playtesting and refining. Working title was “Psy”.
