Mr. O's approved pack. Let's all hope our computers can run it.
This pack is largely a PO3 modification (some will say clone, I say fork). Adds some personal essentials like Environmental Tech and more. Contains the latest and greatest science mods and some of the larger magic mods, but differs from most in that there are compatibility wrappers between them all to balance the game. The better questing system provides a sort of progression guide. All of this means you can have all the cool stuff from multiple mods, without the wack progression that typically comes with.
Fluid cows are now fixed and can be fully automated.
