I looked at this, and Steam's "more games like this last one you viewed" on my Recommendation page followed it up by pointing me to games-like-this such as Day Z and Skyirm. Gone Home was in there, but I think that only counts because the two games probably annoy the same people by existing.
I have some thoughts on Steam's recommendation accuracy!
Right above furry, I mean freedom planet. (freedom planet looks pretty good though)
I haven't played the finished thing yet, but the demo was pretty solid, and that's coming from someone who holds the original Sonic games to be decent-at-best.
