A small tech modpack centered around the Create mod.
The create mod takes an interesting, more mechanical approach to machines. Instead of placing one block and feeding it power, you need to make multiblock mechanisms with cogs, conveyor belts, gearboxes, and more. The learning curve is somewhat steep, but once you get the hang of it, you can truly create whatever you want.
Along with Create, this modpack also includes Biomes O' Plenty, Quark, CC: Tweaked, and a couple other smaller mods to add some variation to the vanilla generation, materials, gameplay. I recommend using Optifine for 1.16.5 with this pack, as it usually helps with performance, but I haven't done much testing to see how much it helps.
Disclaimer: This pack was made for a small online community I'm in, so unless it gets super popular, there probably won't be many updates or anything.
