I believe The Vanishing of Ethan Carter is an incredible game that shouldn't be missed. Of course it won't be everyone's cup of tea and it's massively story-centered, but if you don't mind this, you will enjoy what is a real jewel of a game and a title from which the gaming industry can learn a lot.
Super Time Force Ultra is a great gaming experience and should not be missed by action-platformer fans. Its funny script including ridiculous missions and time travel stereotypes combine perfectly with its innovative mechanics, assuring a great time.
Good news is that Big Pixel Studios isn't done with the development of this title and its developers have already begun asking for opinions on new characters on the Steam forums. If they reconsider the multiplayer possibilities, this game can become a lot more than what it already is.
