Ooh! Shiny! This looks like it has a great deal of potential! I think I'll be following this closely.
I like buildcraft, but it feels kind of bloated/old to me.
I like AE, but it feels kind of cheaty/OP to me. I like my items to have a physical location, not be stored in some ethereal magic techno-ether somewhere.
I have wanted to figure out logistic pipes, but the learning curve, (or at least, apparent learning curve), turned me off. (Or maybe I was just lazy at the time.)
This feels like it could be something quite interesting, perhaps a smattering of all of these flavors, but more refined and focused, as well as a taste of the redpower tubes I loved so much. Do you already have an idea of what direction you're going to take this in?
One of the few ideas I have for the moment would be to perhaps implement some kind of FORTH dictionary/starting guide via either book or terminal into the game, for those of us who never bothered to learn it before. With a few extra/more complex script examples, like a basic string sorting program or something.
The other idea I have for now would be some sort of auto-mining mechanism that isn't quite as cheaty/ham-handed/simple as BC's almighty quarry.
Maybe some sort of multi-block mining mech/crane type thing you have to design and build/program yourself? That could be an interesting way to improve on buildcraft. I've never quite come across a mod that did in-place auto-mining in a very interesting way. More power compatibility for it, (BC, EU, TE, etc,), would be nice too.
Question, do you have plans to re-implement/re-use any of the buildcraft power functions? Or is this more of a tubes-only thing?
