I have never encountered a game that enthralled me as this one did. After being introduced by a friend - he challenged me for a race to the moon, which, surprisingly, I won - I played this game feverishly every day, some nights. Prepare for sleepless nights and cancel every plan you may have for your life - it will consist entirely of Kerbal Space Program. This game will become your dinner date, your bed partner, your counselor. It is that good.
