I don't remember any issues with the text scroll being too slow, although I do usually prefer faster speeds. I dunno, I'll check again once I get the save nonsense squared away.
PSMD is... okay, I guess! I definitely appreciate the expanded amount of content gameplay-wise, and the story was all right, but it wasn't as good as the Gen IV PMD games' story and more or less rehashed parts of GtI's plot. Postgame story also short and not satisfying, imo.
Mechanically it's decent enough, mostly the same as the others with a few new niceties, and thank god they brought back the ability to do multiple missions on a single trip through the dungeon. I swear it feels like my HP is lower than it was at the same time/level in other games, though (or maybe enemy attacks are just doing more damage? or maybe it's my imagination because it's been forever since I last played a PMD game???). Part of that may be because oran berries temporarily increase your HP by 10 automatically when you use them (even when your HP isn't full), but does that mean they balanced the damage around the assumption that you're going to use a bunch of them? I'd rather have a higher, more stable natural HP and have to work a little harder to increase it than have low natural HP that I basically have to expend items on just to raise it to a reasonable level for the duration of one dungeon. You can wait until you were going to use the berry to heal anyway, then get the healing + the HP boost in one, but given how much damage the enemy can do there's also a decent chance you'll end up burning a reviver seed anyway!
They also added a "push" command that allows you to shove your teammates onto another square... but they made pushing the default behavior when you walk onto your teammates' square rather than passing through, and you have to push a button to pass through them, and pushing costs you additional hunger points so you end up making yourself hungry faster just because you forgot to press B while trying to backtrack, and why are those not switched it is extremely aggravating! I mean, you get used to it, but it shouldn't have been an issue in the first place! In my experience pushing isn't even that useful!
It's serviceable, is what I'm saying. I don't agree with everyone who's going on about it being the best in the series—that's still Sky, imo—but some of the new features are nice, not having to deal with minuscule random recruit chances is nice, and at least it's more fleshed out than GtI.
