well its Create! with a lot of addons and other stuff ive spent 2 years to make this mod pack and its been fun! it has mods to make you get an absurd amount of brass idk why you need that much brass but ok. you can make endless factories you could blow up a village with a nuke if you wanted. BTW this mod pack does't get big updates.
(multiplayer is supported but the pack has client mods too so if you just uploaded it to a server it would not work. open to lan might work?)
