Surprised no one has mentioned it by now, but it is astoundingly popular for an Indie game that came out last month in September.
It's a JRPG with a good twist of humour and tragic elements to make the entire thing a joy to play through. You go around fighting or
mercying your foes which this and other choices you make in the game changes how the story progresses in little ways. It is a really charming game with a roster of very interesting and loveable characters. It's Fan base is quite incredible, already many parodies have appeared on Youtube.
It's on steam with outstanding reviews with 93/100 on Metacritic and costs $9.99 and i think its worth it. I enjoyed my first run of it and i will attempt to complete all the endings.
