Phase 1: The Excitement
Some idiot comes up with the idea of trying to make their own game. Being a bunch of kiddies on the internet, they lap it up like a cat laps up its milk, when it's really thirsty and really feeling like a nice lap of milk.
Phase 2: The Doubt
Some of the less idiotic members start to realize just how big a task making a game is.
Phase 3: The Reassurance
Other idiots reassure them, by making an idol out of some random by passer (Sigfig) and telling them that he is an expert programmer and knows how to abolish the problem of lag.
Phase 4: Delusion
Everyone is suckered into the ploy, making crappy maps and hyping the game on forums they are not welcome on. Nobody realizes that everyone is in fact just doing those two things, and nobody has produced anything looking like a block (except most of ProBuilder's maps) - but they don't worry, because Sigfig is an expert!
I'll be right back to continue the phases, I have some crap to do.
