MMORPG Tycoon is extremely well made and you're adding stuff all the time, but once you have it close to a "final" vision you may want to consider publishing it. I'm sure that if you posted it on Steam for 10$ or so you would get a good number of sales. And they handle distribution of updates and other things as well.

Even if you want your game to be free, you can sell it on their store and give it away free on the site. Plenty of people walked to a store to buy a physical copy of Counterstrike, even though they could get it free (at the time).
