Inspiration for game designs comes to me in all times and places. In fact, I think a designer could make a game from just about anything. Although most of my game ideas are still in the boardgame realm, I occasionally think out of the box about other types of games. Call them "indie" or "alternative." Whatever they are, I think it's a healthy exercise, whether they get developed further or not. After all, it's this kind of thinking that brought us Facebook games, and most of us know how those turned out.
