Now, how the Nether heck do we classify these things? Trying to keep it simple, there will be a build type:

• Build: just ideas for things to build, like rail networks, special-purpose rooms, and power grids.
• Business: these are the things that NPCs will be using their houses or offices or labs for. If you have an empty room or building, choose a business to put the space to good use. Or every business is run by you, so this is where you would do all of a certain activity yourself. If you don't think in terms of NPCs and want a fixed goal, just craft the items, decorate the place to match, and get a stack of each product in a chest, and call it a day.
• Colony: new places to build and expand your civilization.
• Craft: these challenges are mostly crafting challenges for top-tier items. But any kind of factory or automation would be a build instead.
• Trophy: things that are built purely to show off your in-game wealth.

I personally like the idea of adding "businesses" to a settlement, instead of just empty buildings. So, instead of 20 more empty beds, search here and come up with an Aquaculture Museum or Saltwort Farm.

Next, I will either list the mod which makes the build possible, or "modpack" for an idea that gathers items from all mods in a pack, like getting saplings from every mod.

Tech Level: I will try to classify the builds based on the technology levels needed to build them. There are a lot of long-running challenges like the Refugee to Regent Challenge, which have similar tech level concepts (and printed RPGs have had the concept since the 1980s). In super brief terms, the tech levels I will use are:

• Dirt: no tools except wooden hoe; no armor; build with dirt, gravel, sand; you can only smelt charcoal for torches and cook food
• Wood: wooden tools; leather armor; build with logs and planks only; you can only use a furnace for charcoal and food; can make buckets and shears
• Stone: stone tools; leather armor; build with stone; use coal, smelt metals but not use them yet
• Iron: metal tools & armor; minecarts and rails, no alloys yet, starting tech mods
• Redstone: this brings in the Tech Age, you can build any machines that use redstone, use any alloys you can find materials for
• High-Tech (Diamond): diamond and gem tools & armor, Nether exploration; second-tier blocks and devices from all mods, store and use up to a million RF/EU
• Ultra-Tech (Emerald): all Nether materials known, visit the End; third-tier blocks and devices from all mods, tens of millions of RF available
• End Game: every item from every mod is available, hundreds of millions of RF available

Worktables: Whenever I talk about "worktables", I mean any kind of quick crafting or auto-crafting method available in your modpack. Personally, I have made tons of autocrafting factories, but for a better roleplaying feel my favorite tool is the Forestry mod worktable: it will simply hold 8 recipes -- those 8 recipes represent an NPCs knowledge, and it's nice to just keep the table's inventory stocked and click out the items I need; honestly it's faster than most fancy factory setups, and cost only a chest, a book and a crafting table.

MC Versions: Here I will list a range of Minecraft versions where I have personally played packs with the challenge available. Most of my time has been spent playing tech packs from 1.2.5 (the original Tekkit Classic) to 1.12.2. I can't get into exact versions of each mod, but this is a rough idea of where I got the idea or tried it out.

Note: I can't track every version of every mod in every pack, or every combination of mos you might have. These are just ideas. Check if your modpack can do the build, or maybe the idea will trigger something else that IS in your pack, that fits the bill. So, if you don't have the Edible Bugs mod, the "Bug Man" build might inspire you to make a Stink Bug spawner/grinder instead. Who knows. Just have fun.
