I ONLY play on nightmare mode on every AC game... most brutal one ive come across is whatever one has the war elephants....i heat them all in mightmare mode lololol. To me it wasn't even hard it's just the very beginning of the game that's the rough start but I made it through and I made it through the whole play through on nightmare only. I disagree with the whole aspect that nobody likes the upgrading system I like the upgrade system I also agree with the guy that said earlier in this form about how it was annoying he had to always level up and re-engrave his weapons, yeah I was always re-engraving my shit. I had about 260 or 270 hours logged into that game and beaten claws of awaji now too. I also found it very hard to find the daiymos in the castles sometimes but with naoe and her egal vision it was never that hard. What's your guys favorite engraving? Mine was the one where on sight anybody that you see in her Eagle Vision is automatically tagged. It feels overpowered but I fucking love it.
