For me it’s definitely maintenance, largely because my internet is not that fast (~6-8Mbps shared among other people) but also I think package management in general leaves a lot to be desired. Some of it might be better on a new install (or listed in the wiki and I just don’t feel like bothering to do the work) though.
The PS2 version looks great after upping the internal res (not sure how much other stuff like filtering/other technicals has an effect). I haven’t compared it, but like most remasters I’m going to just say the data bloat is probably not worth potential fidelity improvements. That and I’d guess any design issues are still baked in, thus similar experience.
EDIT: In Okami’s case I don’t know if the data size is due to uncompressed files or just due to higher-res pre-rendered videos, but either seems wasteful to me. What is live-rendered and what is pre-rendered just seems arbitrary to me, I’d get if it weren’t viable on older hardware but you’d think a remaster could handle it mostly in-engine.
