Yeah, Baroque is solid as a rock to play (especially in japanese, I can't read a word of it), but totally amps up all of the scare moments that most roguelikes just sort of happen upon by mistake. One of my guilty favs.
I have indeed played Metal Warriors, also. Being able to get out of the suit and run around was really sweet, wish they would do that in mech games more often. Semi-destructable terrian, too. Perhaps not as tight level/enemy/art design as Cybernator (Assault Suits Valken), but overall probally the same shelf-life, I'd say.
Now, the one game I've been trying to get my hands on for years is Gunnm: Martian Memory. Japanese PS1 only. Has anyone in the universe actually played it? x_x
