Taking the B8 but you can't deny that the DPPt engine was godawful. They were fun the first time through but trying to replay them is painful. Saving takes for-fucking-ever if you interact with a PC or catch a Pokemon beforehand, the games run incredibly slow, and some things (like having a fire type E4 member in a region with almost no fire types) just seem terribly thought out.
4th gen had some of my favorite designs, the coolest events(even if they didn't all get released) and the ever important physical/special split, but Jesus those games are awful on the whole.
