Maybe what I'm trying to get at is a central gameplay feature that allows you to play as different characters with different goals, but still have an essential core experience. (Ie. You are the good guy > so you rescue power-stars to make sure the bad-guy doesn't get them). If you are a bad guy, you collect stars to make you more powerful. In both cases, the 'game goals' revolve around the power-stars, but the *character goals* differ in how they use and interact with them. -- This idea is all very well, but I think that it is a bit dull to just have a game about collecting *OBJECTS*, or related to locating these objects. It would be nice if some of the goals reflected character's goals and involved other characters. For example in Toy Story Woody goes to rescue Buzz Lightyear because it is his fault that he is in the situation he is in. Any ideas?
