It was a part of one of the THQ Nordic Humblebundles, so you could've gotten it and many other of their games from that.
That’s the bundle I purchased Deponia in. Still haven’t played it. My question is if it’s a decent game why have they not released the other two in the series? It seems like the third game completes a trilogy while the fourth game runs parallel to other two from what I’ve read. Maybe they’ll release a complete version like they’ve done for PC at some point?
