Working Designs was just a western translator and publisher, not a developer.
The actual developer of those games was GameArts, and almost everything GameArts ever made was excellent, wither attached to the Working Designs label or not.
One that springs to mind is Urusei Yatsura for Sega Mega CD. It's a Japanese adventure game that absolutely requires understanding of written and spoken Japanese, but if you can do that and you're a fan of the greatness that is Urusei Yatsura (where I get my avatar from) it's a must-have.
btw, Wraith Storm, your sig is from that Xbox 360 From Software game Bullet Witch right? How IS that? I've owned it for a good amount of time but never really played it.
