2.) Marketing is a complicated issue and is a large part of what whats games successful or failures, there’s been a lot of talks and write ups about this, way too much to fit into a few sentences. And there’s different approaches as well. There’s the weekly/biweekly/monthly updates approach where you are constantly updating potential consumers, and there’s the media bomb approach where you try to make headlining news on a bunch of different game news sites. You can try to do both as well, they aren’t completely mutually exclusive, but one approach might work better for certain types of games. Same games are ideal for kickstarter and greenlight, but I would suggest trying to have some sort of prototype before doing a crowd funding campaign.
