I think I found a game which will make McMoist really happy.
It is kinda explained here:

Remember when he made these Sims SpA stories? Well - this game is all about storytelling between two players - it's a point and click adventure game where one player interacts with the world and the other player plays... THE WORLD. :-D
Basically this means that the adventuring player can literally do whatever he likes since it's up to the other player to provide the response. It will be glorious - it looks to me like all these clunky play-pen&paper-RPGs-by-net programs but much more streamlined. ^^
I assume you will be able to make your own pixel art too.
Oh boy, the possibilities are endless. No need to order it, McMoist, you get two copies per order and I preordered mine already. ^^
