Got curious: How are you new ideas formed and how do you actually get to begin building a product? How much do individual contributors really have in terms of a say in how whatever you build works? Who's job is it to come up with games and ideas for games? Always been interested in that type of work and wondered who's in charge of thinking and planning out entire games -- is it a PM or a group of PMs?

Big companies already have well established titles they can milk for decades just by throwing in more detailed textures.
