this mod pack is some what big but the reason why is because it has a lot of quality of life features alongside the main features so as an example JEI, Cloth Config API, AppleSkin Etc.
Note: Before you were ask yes the thumbnail was made from AI and i know it's not a good thing but i really don't have any choice i'm not good at art and trust me if i was i would've tried and i don't have money to pay an artist to do it so suddenly IA was the only option
also just as reminder you can also make tanks and there is the Eureka mod so you can effectively just make blimps and planes passing the create bot but you still need to create mod if you want to automate the process
there's so much more to enjoy in this modpack but i would be here all day and you would be here all day reading this so why not play have fun and enjoy whatever world you make PS: this is my first ever modpack
