I have all but 3 of the production crafting cards, but haven't got that one yet. I'll keep trying.
There has been talk of a use for spare parts for a while. It would be good to have something to do with them. I have loads of some. Gold panels are the rarest for me and they are what I need for those last 3 cards.
Wow so I really lucked out today! I guess the randomness of it all deals you what you got.
It would be interesting to see how they fit the use for spare parts into play. There should be a new game mode coming along with it that requires instrument use. Something to look forward to. Like we don't have lots to keep us busy with already! π
