Holy crap those are awful. After getting the symbolism explained, it seems like you would need to be a big fan to understand them and leaves out the person who is running them for its own sake. They might have been OK as the center of the medal but, as a stand alone, they are terrible
Wouldn't you need to be a big fan of any of these IPs to enjoy them? I did Tink this past weekend and I thought the medals and theme were boring and borderline tacky. I haven't run Avengers weekend yet, but the Infinity Guantlet medal makes sense for the avengers.
