Yeah, the music in the condemned tower is possibly my favorite track from that game. It's true that it isn't the strongest CV soundtrack, but I find enough likeable stuff in there to listen to it every now and then. The BGMs from the Subterranean Hell, the Condemned Tower, the Clocktower, the Pinnacle, and the Boss theme from the Puppet Master and Gergoth are all really good, at least in terms of catchiness. I think there's a lot more of a "sorrow" theme to this OST compared to Aria's, especially in tracks like the Condemned Tower and Pinnacle BGMs. I agree that Soma isn't developed as a character at all in DoS. It never bothered me though. I guess I took the game as a direct continuation from AoS when I first played it, and so I didn't really need a character arc. I remember feeling pretty sad for Soma the first time I made my way through the Pinnacle, though I don't recall exactly what went into making me feel that way.
I don't have much more of any relevance to add here. Ridureyu's write-up was, again, a fun read, and thoughtfully-composed too. I'll be looking forward to the PoR discussion, since I still don't care much for that game compared to DoS and OoE.
