It's also the fact that, as a completionist, I want to see the scenes organically so I have full context instead of just seeing the scenes in the recollection room. It would make the scenes hotter and more fulfilling. It's also FOMO hitting so I want to make sure I'm not missing anything that is "missable" in a normal playthrough (this doesn't count scene variants. They are by nature intended to be seen in multiple playthroughs).

While I did replay the whole game on easy mode, to make sure it's the correct quickest path, that means that I haven't reached high depravity value so can't see all the scenes, or don't know when is a good place to farm SP early to have money for healing items. The good news is that if you don't use Radiance Bomb in fight, you don't have to buy even a single one to progress, you have a good opportunity to get it for free before every time you need one.
