Way of the Samurai story progression has yet to be mimicked or topped, so I'd say they are way ahead of the curve there. Even the core gameplay of it is still advanced. The actual combat is simple, but all the different styles based on the weapons you get are awesome. Still, their games do look pretty bad. Their best looking game ever is probably Yuusha on PSP, but that is a 2D game.
And Samurai Western was fun.
Oh, and the PSP port of WOTS samurai is apparently a bit messy.
