Tools, item transport, storage, invincibility, flight, automated mining, teleportation. These are a few of the goals that I think most tech mod players strive for early on. In Monster, theres usually only one best way of doing any of them and a bunch that nobody ever uses. And best is what is cheapest and easiest in most cases. It would be easy to minetweak certain requirements in between each of those goals. A mod like Galacticraft is perfect for gating overpowered machines because its a pretty big undertaking and could be minetweaked to require a whole slew of machines from other mods. Which is the very thing that made tech mods interesting in the first place. You need machine A to make machine B to make machine C...wait what did I need C for again and why is my base full of machines?
