ok, at first i REALLY GROOVED with the tight minimalism of this game: no costs to lay down tracks, just pure focus on making efficient production lines.
Then it started to really invade my dreams, and then my waking thoughts. like, in a bad, intrusive way. I had to stop even though I really loved this game. It's good! it's great! it was too much Raw Stimulus for me and ended up being net negative for my life.
