1) I saw mentioned earlier the hard/easy difficulty for quest lines. I saw that one quest which allowed you to choose one or the other and get different rewards back. Does that choice affect more than just that one time quest choice? (i.e. things you cannot see, etc...)
2) I don't know if I mentioned this before, but I have an issue with pneumaticcraft and I think I've pinned down on what that issue is. It all revolves around the pressure chamber. You cannot automate it easilly since everything revolves around IT'S filter, etc... ignoring completely anything outside of it. For all sakes and purposes, the most you can do is just itemduct to/from chambers and do everything in the chamber interface itself. I can see why it was done that way, especially on the out facing one, but generally, this ensures alot of tedium as you switch between jobs and if you have to do something different, your choices are to either a) make another pressure chamber, or b) change the one you have back and forth each time you want to make something different.
For example, to make plastic, that's simple. use the filter for outside facing and set to contains plastic and no matter what you put in the input, seed wise, it'll make some plastic and come out the other end. But if I suddenly want to make something else, yeah, see above. I was eager to test out SFM on this and found it's worthless for it. Especially since it blocks the interface completely.
Mind you, setting up blood magic to do something similar is just as bad without sfm. For example, to auto-create those things you start creating from stone. I end up making a crap ton of first tiers, then switch over to 2nd tier, make what I want, then third tier, etc.. Problem is that you are filtering off of either what you are putting IN or taking OUT. I think SFM would handle that tho with some redstone receivers and switches to choose. But here? No such luck since it's marten's interface and that's it.
Add that into the fact that EVERY frigging thing requires PC to advance including all the dynamos, most of the generators (there is pretty much all the power generation including the big reactor controller) and then you have the machine casings and anything else requiring the PRC cards. I just noticed that all the MFR upgrades require the plastic as well, so I'm sure there's others.
My strategy normally is build exactly what you need and make the thing you want. Here? It's more like, ok I'm going to stockpile 4 stacks of each plastic and wait until that's all done and proceed to make the sub parts, then sub sub parts till I have stacks of everything to make what I really want since stopping/starting to change out stuff would be a royal PITA and prone to mistakes.
The only other option I see is making individual setups to do one set of tasks. Is this what most people are doing? I think marten needs to work on integrating other mods filtering to automate things better so people can actually work with the tools they have not the new ones that have limited scope/purpose. I stopped playing the last version of CL when I got to this point out of frustration. I'm going to press on this time tho since I want to play this pack moreso than any others atm. Plus, I love living in mdiyo's ship :}
3) I found no way to automate the smeltery or the deep tank with SFM (big sad face). I can think of a way but it'd require a bunch of drums and a larger area than I planned for and alot of setup which I will probably do at some point but not now. Bummed about that but loving SFM. Haven't felt the need to proceed to AE yet cause of that which is very cool.
4) that TC scythe works great tho one bad part. It shears leaves but never drops saplings, so you still have to crook enough to make your trees back. I was getting a few saplings with the shears previously thus I have a stockpile. Makes farming trees much easier.
5) Lastly, while reading all the posts about the cities and structures made me think of galacticraft and those silly alien villagers. I know that jaded made that purple wolf 'cat'. Maybe make some colorful villagers to go in those villages or can you just nbt spawn eggs? Maybe some lava tanks made out of stone that would have random leaks in them to flood areas to ensure some climbing is involved to fix those leaks would be needed, etc... Make one city have all spider spawners and jungle spider spawners cause who doesn't love being chased by a horde of hungry slurping spiders?
