I thought you had to be great in the computer fields before your friends started asking to make their idea games. Just happened to me this morning.
Friend: Hey let's make an MMORPG!
Me: Bro that would take years...
F: Hmmm... fine then just an RPG.
M: *in my head* cuz that really changes things, it's still an RPG...
M: Lemme hear your idea
F: *proceeds to describe Fallout /but better/
F: And I'm willing to learn game design an hour or two a day

Idk how to make him realize that it takes money, time and more than two people!!
