UFTS Anthros
easy - Eager to sell or trade, but still won't accept malicious lowballs.
medium - Standard to little reluctance on surrendering the design.
hard - Very tentative on trading or selling, will likely reject offer unless highly desired.
extreme - I don't want to necessarily get rid of these guys, but I'm also not fully committed to taking them to grave with me. Will likely have to be bribed to surrender them.
