I haven't gotten into specifics yet, but I can try to articulate what I think the feel should be and I'd be happy to get some input on it. To be clear, the minipack is already in progress, I'm talking about the larger pack to follow, as assume we're on the same page on that.
First, the stuff from sprout. We're not interested in the questing, really. We've done quests before. It's ok. But it has two things I love. One is the best set of tools for creative building that I've seen in a pack. Mainly things like the half slabs for everything, colored blocks, extra bit manipulation, etc etc.
And secondly, I love that it keeps the RF production somewhat grounded at least at first. So I wouldn't, say, build myself a nice little solar panel that passively generates 4096 RF/t and it's basically free power forever. I intend to encourage an actual progression that encourages many different types of power to be used. Ideally, I'd kind of like to build a rainbow generator. But, I want something to progress TO, so I still want the end game mods to be out there, I'll just have to put them behind some kind of a progression wall.
I ultimately want it to come off like a group of people wake up naked in the middle of this world, and it starts off as gilligan's island and ends up with a complete mastery of the elements.
It will also feature minecolonies as a main proponent of base-building. The idea, same as my plan for Sprout, is to build a working castle village populated by the minecolonies citizens and my individual buildings that will be odes to different mods. I also still like things like level up and whatnot.
But, I also want some of the flexibility that comes from the kitchen sink packs, which does mean including some magic based mods, even if not jsut for me, but for the other two people on the server to play with.
And I will definitely be scrutinizing world generating mods. You know how much that means to me. I don't know what I'm going to do yet, but it will most likely be something I haven't done before.
