Stupid question time. Firstly, I'm very curious about this mod. While I love graphics mods (I find Remako for instance revolutionary) I'd always wished for mods that adjust the storyline or events or add new content without breaking canon. Example: I loved the idea behind the Jessie mod, although when I tried it unfortunately it didn't work properly.
Back to the topic, two or three days ago I installed 7H and Remako but spent almost an entire day to get them working, and I did! Using integrated graphics too which I heard would definitely break 7H with graphical mods. Great experience. However, I hadn't noticed New Threat because I found its description on 7H very vague and from the name assumed it's a hardcore mod. (After reading up on it, it sounds awesome.) Big mistake. I believe I've invested close to nine hours into FFVII and I'm currently at Fort Condor. My question is: would it be a big deal if I activated the mod this far into the game? Compared to the hard work you've put into this mod those nine hours are nothing. However, I'd probably wait a few months before restarting the game if I must do that.
I also must ask about the load order. I've read about how to prioritise it (ordering by the mod category) but since this seems to contain some of everything, should I place it at the top? Here's my current mod setup: https://pastebin.com/9L7efFg8
You could activate it midway, but you'll be missing a lot of intended Materia like Barrier. I think beyond that it should function correctly though your EXP might need a level up or two before it corrects a visual glitch with the gauges in menus.
For mod load order, it should be closer to the bottom as NT is a gameplay difficulty/story type mod.
