Oh, I am definitely not wanting backers to be put out, incentives are incentives but yes it would be nice to be able to get them (for a price) at conventions since not everyone can afford to back projects but I have bought everything that TAG has produced for LoA, so far, and stuff you can only get at conventions, I am going to be hitting the Games Expo every year from now on 🙂
As for the cards, I misread the kickstarter page, I thought the bolt, cog and piston card sets were actually extra sets, not part of the main set (and unlocked via backers). So I thought there were special cards that came extra!
