I actually have the DeviantART fan base to thank for getting me into the game.  Saw so much fan art of the characters that I decided to play the demo, and I instantly committed to buying the full game.

And having played its three major endings, I don't regret it at all.  At its best, this game emotionally moved me more than any game I've played in the past.  Toriel is a great example of that.  Rescuing me from Flowey's attack, taking me into her home...and even when I made it clear I had to leave, she gave me a farewell hug.  It broke my heart to have to leave her behind.  She was a lonely woman.
