I think Wreck-Age has a solo play option?
Kind of; Wreck Age as published can be done with a single player, but not a single person. It needs 1 player plus the Narrator (GM).
Wreck Age is (IMHO) the best PostApoc game around for depth of involvement and as it can function equally as a pen & paper rpg its characterisation is incredible. This detail tends to carry over into the skirmish side a bit too much though for most gaming groups.
If you have a group of players who meet consistently and regularly it would be great for a campaign. However for most groups with irregular meetings and attendees it is just too complex for pick up games.
I love the game, but never play it (as I said before ATDE is kind of Wreck Age lite).
The figures produced for Wreck Age are exquisite.
As for the KS fiasco, yes, dealing with Hyacinth is a challenging experience. Good people but artists and gamers first and foremost.
