Hey Ced30! How are you doing? :)
I'm glad to see you are enjoying the assets. Plans are in place to expand the series through thematic expansions, allowing for a deeper dive into various aspects of RTS games, such as production chains or defence-focused features, among others.
However, Minifantasy Patreon community members are those who suggest and vote on new content. The plans for new RTS content are there (there are already several main asset packs suggestions for the RTS series), but they will arrive depending on the community's majority interests.
