Currently, the big bertha does not require any of the fancy materials that the normal artillery uses when the space exploration dlc is installed.

Imo it might be worth tweaking this recipe if SE is installed so that the bigger artillery isnt cheaper than the normal one.

EDIT: Or the crafting recipe could simply require an artillery to craft, then it would effectively auto-scale the crafting cost.

Yeah, it's on my to-do list. But I haven't played Space Age yet. So I don't know which items to pick. But I like the idea to require the base artillery.

I have made a PR here https://github.com/marvint24/bigger-artillery/pull/5 :)

Thank you! I merged your changes and changed it further (ingredients and tech), so that the base game and Space Age is balanced.

Thank you!
