I seem not to have designed any two player games. To combat that, I thought it would be interesting to try an experiment - a reverse competition.
Essentially, what happens is that people submit themes / mechanics / etc ('The game should be about a couple who are fighting about where to put the teapot on the living room table. The game should be tile laying and involve a gadget.'). For each submission, I'll write up a proposal for how the game would work. People vote for which proposal they want to see. I attempt make a game following the winning proposal, and then put it up on the Game Designers Workshop for everyone to have a laugh at.
If you think this looks interesting, reply with a concept.
A truly noble (and entertaining) pursuit!
The players are rival Ant colonies, besieging a picnic. The Red Ants and Black Ants face off on the familar red & white checkered picnic blanket, vying for the tastiest morsels at the picnic. Pieces of food worth various points are scattered around the blanket, some quite a bit larger than others... Larger pieces are worth more points, but require more ants to drag back to their anthill.
