I may or may not have the energy to write a more detailed post later, but for now: Thank you. What a spectacular achievement this game is.
I may do another run through after a while, with a different play style -- I did this one as a battlemage, the sort of thing I naturally fall into if it's available -- but I need a break first. This has absorbed me for over a month of virus-induced sheltering in place and it would be good to focus on something else in awhile. Assuming I can tear my attention away at all. If nothing else, the music will stay with me for a long time.
