That's quite the price drop.
Thanks to the infernal steam trading cards I did go on it again fairly recently. I Saw a few people now and again but that was about it. Even at an Arkfall event I believe there were only 2 other people there. However I didn't go to all the areas so I can't really claim definitive proof. Maybe I just missed them all. After a couple of hours though I realised that the game still just really bores me so I left it to get the rest of the cards and haven't touched it since.
