Dreams by Media Molecule of LittleBigPlanet fame is quite of an experience.
A social network where users can create their own games and share them with others and while there are a few duds here and there, the best ones stand out and shows on how creativity a person even with the tiniest bit of development experience can create something unique.
Dreams is the perfect all in one game package. What can you do in it? You can play games made by other people, you can create music and sculpt your own characters, you can make a painting, the limit is your own creativity. Media Molecule have made it relatively simple to get started making your own games with a creation tool that is deceptively simple at first glance, but packs a lot under the hood when you're ready to take a dive. I find the community aspect to be important to the overall idea of Dreams, as you can comment on other peoples games still in progress, use assets from games you like in your own game; participate in monthly competitions and so much more. For $45 you are basically buying a video game maker, music maker and a console full of thousands of games all in one.
