Me, myself and I.
I think 2015-2016 for me too. A big fan of the computer, logic and rail system, I enjoyed making contraptions and machines. It was exiting with new updates coming out regularly with new features. Oh and I loved it when the etheral rails and the fleet system came out. I could see so much potential in the game if those were expanded on. Especially if humanoid MOBs and non-humanoid, were expanded on we could probably use them to expand the game play more.
