Expansions will be coming in the future. Yes your list touches a lot of the things in my notes. It's good to see it though, so I know what you'd like specifically so I can add up the priority on this.
While I am just concepting the exact composition and designs of the new specific sets, I think it's fair to say that hammers and scythes might be some of the next thing we might see some deeper expansion for. Spears might follow.
Guns actually saw a lot of expansion in the survival horror, steampunk and weapons set, each providing 5 guns. There are single ones in the adventure set and survival set and basic set as well. So in total like 17 unique guns. Is there something specific you are missing?
The armor & clothing topic pops up constantly, so I think the first armor/equipment set simply was not enough? Is there anything which you don't like about this set? would like to see improved for another similar set? Are there some pieces of gear you miss specifically?
Thanks for the feedback.
