We're planning on bringing A World of Keflings to PC at some point!
It'll be interesting to see how the sequel will transition to PC. A Kingdom for Keflings already had a PC port, which was like the XBLA version minus the Avatar support, so you just had to pick from one of the pre-existing giant characters. The sequel just had Avatars as playable giants (or Miis in the Wii U version), so I guess they will need to make new distinct giant models for the game in order to release it on PC. Microsoft have already stopped supporting Avatars except for preservation for old titles and Nintendo seems to be putting aside Mii support with the Switch, which makes me worried if they will be dropped entirely by the next system. So i guess going forward, even if they continue supporting said platforms, using just original characters as protagonists is probably the way to go.
