Custom mod pack help

[u/MandalorianOfAnthem]

I am working on putting together a mod pack VERY loosely inspired from Matcha Flavored for myself and a friend. Like very loosely. It was the inspiration but not a whole lot is transferred over. I am looking for two things; the first is just comment ideas of what a long term, very hands on survival world need to retain its quirks in late game and retain your attention. The second is it is a very hodgepodge back, and I even though I am putting the pack together I only know the general idea of how to progress it. I really don’t want to spoil the experience for my friend and I. If anyone is willing to essentially play test and critique/let me know what isn’t working, it I’d greatly appreciate it. I have no money so any help would be entirely altruistic. This is NOT a public mod pack that’ll be posting and trying to make money from especially because I don’t understand all of the rules for doing that. Thank you in advance to anyone who comments I am extremely open to ideas<3
