Hey, I think you might find this interesting: http://en.wikipedia.org/wiki/Minecraft#Commercial
...To compare this to another Indie game we all know about. In the first month of release, Minecraft sold 1,000,000 copies. Advertising was by word-of-mouth. 25,000 of those were in the 24 hours following a weekend of play-for-free.
I can't put into words how excited I am for Mythruna. I think this game will do as well or better than Minecraft.
Lets just be skeptical though, say you sell 1,000,000 copies in the first year. That's $15,000,000 - enough to live very comfortably for the next 100 years.
Mate, take the time to let your dreams become Mythruna reality, and I predict you will be very well off.
