Besha(?) Ruins is pretty blah, yeah. Every preview and video of the game involved the same area and boss fight, so the locale did nothing for me.
I've tried the demo again today, still excited for the game, but I realized how the camera really exposes the frame-rate's choppiness. By the time I was done, I was sick of it. I also feel the monster collecting aspect will get boring and repetitive quickly, if the uselessness of 75% of the monsters in the demo is indicative of anything.
