They release a preliminary feature list to this little community, and a couple hours later it's plastered on the front page of Blue's News and everywhere else as promised features. Unless you're sure you can pull them all off and that they'll be fun additions to the game, that's a bad idea.
With all due respect the game has next to no media coverage whatsover on any major websites.Most small games developers and publishers have no issues talking about design way in advance because most adults do not react that way you suggest.
For a good current example of adults behaving as 2 year olds, read what's being posted about Disney buying out Lucas Films, LTD. Real adult reactions there.
Sorry, but I've experienced too much of the Internet to believe that adults won't throw a tantrum when they don't get what they think they should have, it happens far too often.
I really do not want to hunt for it: are they really being rude to Lucas or Disney or both?
