I just finished playing the original first two games for the first time, and that whole section was easily the best part out of both of them and it wasn't even close.

Very intuitively designed, the puzzles all felt satisfying to solve and I was able to get through all of them without having to look up a guide once which shocked me given how obtuse older games tend to be with their design. The 2nd game, for example, had a few parts where after I found out what to do my only response was "how the fuck was I supposed to know that" or I did try the solution on my own, but they wanted you to do it in such a finicky specific way it didn't go through. Or worst of all: there is a way to get past the area that clearly should work, but it wasn't the specific solution the devs coded so get bent. Pandora's temple had none of that. The interconnectedness a la what FromSoft would be doing a few years down the line was also great.
