Your market is online. You can't charge a lot either, and I'd think you'd need a small collection of games like this. You charge a fee for access to them over the net. Plenty of people get bored at work or at home, and need something fun like this to occupy their brain. At work, people can't install big 3d games or even play them and get away with it. Some people aren't in to serious 3d games or their rather high costs as well. So yes, market it right, and you can sell it.

Think of all the people who addictively play Minesweeper, Hearts, and Solitaire. I dare say, this is much more entertaining than that!
