it's remarkable how the community has come around on DI. When the theme and feature set initially leaked, a TON of people instantly proclaimed it a flop of epic proportions.
personally i love the game -- it's simply a lot of fun to play. great flow, satisfying shots, tons to shoot for, and the missions and modes don't get old because there's so MANY of them and they come in more or less random order, unlike some games that can feel relentlessly repetitive (*cough* OKAY WHO BROUGHT THE DOG *cough*). Overall, JJP really knocked it out of the park in terms of gameplay on this one.
