Honestly, I enjoyed this so much. The original [redacted] Life was great - it used clever programming to move the story along, and the story itself was intriguing, but it missed out on the more emotional side that it could have gotten into. This is exactly what the original game was missing, I think, to make it go from a great game to a nearly perfect one. I think this is the part where I say "headcanon accepted." c:
