When the Microsoft Store first came out, I remember they went around college campuses offering $100 per each app submitted to the store. This multiplayer version of Conway's game of life is one of the first apps I implemented and cashed in. I had previously participated in a hackathon that had us implement this version of Game of Life, and I thought it'd make a good app. Sadly, it looks like it's been removed from the store by now.

P.S. The Microsoft representative didn't seem to have much confidence in the quality of apps submitted. He sold it to us by saying that it was just for growth and that they were trying to catch up to the Apple store, which had already had its period of growth with "useless Fart apps". He even offered a "whack-a-mole" style template game that you could re-theme with different images and submit for $100.
