The 3DS games weren't necessarily bad, but they were full of missed potential. Coming off of the massive BW2 postgame it's especially noticeable. I'd honestly include LGPE and PLA in this missed potential category as well. All those games needed DLC more than SwSh. The Crown Tundra areas were fun, but the main campaign of SwSh is severely lacking. SwSh wasn't a case of missed potential, it was just a bad game overall. BDSP is also bad because outside of the expanded underground it doesn't innovate or move the series forward in any way.
