You're not alone in enjoying the gameplay of OR/AS better than Sun/Moon. I haven't gone too far into Moon, but at least three-quarters of the time I spent in that version was going through completely unnecessary cutscenes, much more frequent and longer than any previous games. (Like I keep saying, if spamming long cutscenes is necessary to help younger players, how were we able to survive in Red/Green/Blue/Yellow when they first came out, since most of us were 7-12 years old when those games were new, especially considering that generation was choc full of glitches?) Sure, Gen VI had its share of such things, but they were far less frequent compared to what we have now. Also, it seemed to me the features in OR/AS were more exciting to me than in S/M, particularly DexNav and being able to register key items to the D-pad.
I can't seem to motivate myself to continue Moon, and have thought at various times about trading that game in. I enjoyed my first time playing Alpha Sapphire much more than I have so far in Moon.
