I’m not sure if any game has had so much of an effect on me as To The Moon.
If you’re at all interested in video games with stories, and don’t have the trappings of what you would expect from a game, I heartily recommend buying it and devoting an afternoon to playing through it. Seriously.
To leave on a quote from Rock Paper Shotgun:
I can think of two games that have ever made me cry, and have a nagging suspicion that there’s a third I’m forgetting. In 30 years of playing games, it’s not a common factor for me. But add another to the list. I sobbed twice during To The Moon. And then a third time when I told my wife why.
