I generally prefer to play on the original console, but it's basically the same with a controller. Plus, e also have an option to use high-res texture and overall improved graphics, if I'm not wrong, so that's great.
And yeah, I imagine it must have been easier to play. Well, RE has never been much about puzzles, they're only there to make you even more anxious because gosh, why am I losing so much time here when there's a giant scary dude after me that could crash in at any time?
The great thing about horror games is that, after years, even though they're not truly scary anymore, they still maintain that eerie atmosphere that keeps you alert all the time. It's less about jumpscares and more about "This place gives me the creeps". That must have been the case.
