You're completely insulting the entire development team, not by saying it's dumbed down, but by saying it's a cash grab. Do you really think they would have put this much work into a game just to make a cash grab? This facebook page is pathetic, and doesn't address anything other than your personal angst over not liking the game.
You had a chance to try the demo to see if you liked the game, you had a chance to read all the reviews, you had a chance to read the forums to see what it was like. You don't deserve any money in return, and asking for some is sad.
