I'm sure we could get Ros to program some freeware or something.
We're gonna make tons o' cash with the freeware!
More than you'd think. Linus, a Finnish university student, became a multimillionaire overnight solely by developing (and leading) an entirely open source project which he never sold.
That is the thing about software, selling "licenses" is usually short sighted. Selling support, service and function is worth while. Cripping software out of greed hurts everyone but the pockets of lawyers.
However, "freeware" is evil. Freedom is more than just cost. One can sell truly free software.
For example, how much does it cost to use Google? How much money does Google get each year? Google released an open source operating system for mobile devices, and it is taking the market, the software is free (not just in cost), yet, Google profits. It also uses Linux...Linus's university project.
That is how freedom works. Fewer lawyers, more money and code.
About the game, I am capable of programming games, although I do not make games (they are not interesting to me, and even though they have some sort of glamour, they are the most boring things to program). I have no skill (or desire to have skill at) graphics. I work with data, not eyes

User interfaces are just a necessity because at this time because God did not design us with standard interfaces. That is probably for the best, to avoid compatibility issues, but it results in quite a few kludges in implementing such interfaces!
