How do you know its an one man OP ? considering how big the updates were ,generaly 3-4 times that of most other developers + much higher level , and we know many developers utilise team work.Its quite likely guy had hired hands at work especialy considering how much the quality and quantity increased over his previous games , does he need to advertise that ? No.
My calculations of possible monetary gains were far below what I think taxpayers really should have contributed.
but the developer, should at least mention that update options (or not), so that its users definitely continue looking for this game.
Maybe the expectation will generate profits with new users who are excited about a future contribution.
The quality of the game is unquestionable and that is why we welcome: 12 million VISITORS!
I also expect new versions...
I use an English translator.
Good luck and end of discussion on my part!
