A bit of feedback- overall, the gameplay is fun granted difficult. One thing i personally think could be changed is the order in the quest book. I don't think the main quest lines should all be gated behind 15 bookshelves (and even the enchantment table when those diamonds could be used for tier 3 runes or something), it takes too long to get that stuff when you can already make good progress in all the mods without more than 6 books (3 for the Thaumonomicon, 1 for Botania, 1 for IE and 1 for Rotarycraft). The gameplay is still fluent, though, and doesn't stray far from vanilla standards until you get invested.
