To The Moon
I actually don't want to talk too much about this one. All I'd do is give too much of the story away. You need to go in as blind as possible to fully enjoy it. Well, maybe the basics: You play as 2 employees of a company that is fulfilling the final wishes of dying people by manipulating their memory of the past. And in this case the person wants to go to the moon. Why? That's one of the things you need to find out in this.
Gameplay is minimal. The thing is completely story-focussed. You explore the Patient's memory for enough clues to go on in your quest. The game hast some humorous moments but for the most time will make you cry. The reason for that is the excellent soundtrack, which you can and should get with the game. If you didn't, you'll get it after playing the game. Trust me. It's phenomenal.
Play time: about 4 hours.
° That horse riding
° 640x480 is the only available resolution.
° The Soundtrack has the original loops from the game. Some tracks do end in a really strange way.
Everything else. Trust me. Once you start you'll not stop for anything until it's done. Not even for updating the Steam thread.
