Nah. Those games were never that mechanically demanding, they were however demanding patience and for you to relearn how to play an action adventure game under the rubric of a stamina, slower paced game. But by and large once you figured out that you could beat mostly anything by hugging the right side of any enemy, it was pretty easy.
Yep. At the same time though, trial and error, and pattern recognition was considerably harder than what you would see in most games around the same time on the normal and even "hard" (the new normal) difficulties. They were not really reflex based games as much as figuring out what works and not making dumb mistakes afterwards. I legitimately didn't have any real issues with Demon's after the first two hours other than Flamelurker (fuck that guy), Maneater (fuck them and the camera they rode in on) and parts of world 5-1. Died a few times to the Red Dragon before cheesing it too. Otherwise, I think I only actually died at most two times per boss. The world tendency and more obtuse aspects of the game were where much of the actual difficulty had lain.
The camera sure wasn't.
