Nope, my post was just meant as some random fact. You can easily put a price on an infinite stream of constant payments. I don't believe the project is able to generate an infinite stream of 750$ payments. But if it could, that would be roughly it's value. By the way, for an investor it does not matter how much effort (1 year, 5 years, 100 years) the author did put into the project. For the present value of the project only matters what monthly payements there will be. If someone can forecast these payments, he can also put a price tag on the project. So it might also be, that there is no more interest in the game in one or two months ... then it would be roughly worth 0$ to 750$ (even if it took much effort to implement it).
