I bought Dust: An Elysian Tail not because it was furry, but because of TotalBiscuit's review saying "If this game had come out ten years ago, it would be a classic". The art is great, the music is amazing, and the game as a whole touches on very serious subjects for something with a rating of E.
I would not really become a furry until a year and a half after buying the game.
I probably would not get involved with furries if it weren't for my fascination with Halo Reach when it came out. Figure that one out.
