Just buy this game, if you have an Xbox, PS3, PC, iPad or iPod then get it. It's probably the best game I've played all year and everyone should experience it. It's an episodic game meaning that it's split into five parts and each part is like a TV episode, the story and characters react and change depending on your actions. It's not an action packed game since the focus is on puzzles and character developement. I'm not doing a good job of explaining it but play it regardless, there's a retail version coming out in December so not having a console hooked up to the internet is no excuse.
Now excuse me while I go into a catatonic state brought on by uncontrollable feels while I recover from the ending.
