borisburke: +1 on unskippable cut scenes and producer idents at launch.
Same here, but with disk speeds being faster, I'm of the opinion that load times should be considered obsolete. I'd like to play the game right *now*, not wait a few seconds for it to load.
MeowCanuck: 6. Unable to switch out your main party leader. Whenever the party size is big enough that I have to choose my party members, I'd like to be able to replace the party leader. Not only could this open up a dozen more team combinations, it also barely changes much of any story anyway since it's inherently assumed the others are following closely behind or ahead of you anyway when your team does split up. Even CSH (2017) has this problem.
I had this issue with Grandia Xtreme. It's particularly bad when it comes to XP distribution, as you can't easily level up your characters evenly when one particular character is *always* in your party, taking a share of the XP.
Even worse is when the main character is male, preventing me from using an all-female party. (Also annoying is when a game has plenty of male characters, but not enough female characters to form a party.)
I could mention that, in Dragon Quest 8's 3DS version, which adds new playable characters, you still can't remove the main character from the active party, even though you could in DQ4-6.
MeowCanuck: 5. Backtracking. I don't mind if it's a couple times, but within reason please. If I have to go back 5-8 times for repeated quests, there's something wrong with the game. TMSFE (2015) is a good example.
Corrolary: Diallowing backtracking. I *hate* it when the game doesn't let me go back to an earlier town to buy a useful and interesting consumable that isn't sold later, or when an area becomes permanently inaccessible, resulting in missable items or lost opportunities for XP/money/ABP/stat farming. When a game makes it harder to level up just because you go past a certain point, it creates a dis-incentive to progressing further in the game, which is bad game design. (SaGa Frontier 2 suffers from this issue; after the Hahn Ruins, you don't find a spot as good for learning advanced techs until the start of the final generation.)
