Heavy Rain came out in February and had you play as four characters who are all involved in some way with a series of kidnappings and murders. The game and its multiple endings were generally well received, but some had issues with the control scheme. See, you don't control Heavy Rain like a traditional third-person game. Here, you move characters around environments and options for things you can do pop up. You can rotate the right stick to open doors, move the right stick up to stand, and so on.
Basically, it wasn't everyone's cup of tea. However, here at E3, Sony's showcasing the PlayStation Move and how it can be incorporated into "hardcore games" – on that list is Heavy Rain.
