From the main series... R/S/E. Basically was a big step backwards from G/S/C... I mean, rival was bland and uninteresting, and why was there no extra region... hell, why was there no link to the previous games in terms of continuity? Not even an Oak cameo? No?
In terms of spin offs... well, I tend to steer clear of the spin-offs, and any I do play I tend to enjoy. I... honestly don't know.
