Hey, thanks for the interest. I don't have much experience with gamedev, but I try to apply the design patterns I would use on a server. I hope to make the code at least partially source code as I have noticed a distinct lack of turn based rpg tutorials for unreal.
Using unreal for the game comes with some perks such as built in support for data tables and save games. This is the main reason why I leaned towards external spreadsheets, I can just import it into unreal and use lookups on it. Using it, I can see the attributes, abilities and AI weights of every enemy and quickly make broad changes. To my understanding this is the unreal way of doing attributes.
I might assemble a combat demo but I would first need to get some sprites as I don't want to ship anything with ai generated images in it. I will see once the core is done if its going to be easy enough to make as it would allow me to get some feedback on how the rpg skill play out.
