God, Abyss and Vesperia were ridiculous with Abyss locking a solid amount of sidequests until NG+ (and still barely hinting at them) and Vesperia being vague as all get out about stuff. Love both games to death and I've got fond memories of doing all of that in them, but it wasn't without some frustration.
The only especially irritating Xillia one to me was. In general they've gotten a lot better about making sidequests more apparent. I sort of miss the vagueness and feeling of exploration that came from the Vesperia and earlier ones (Xillia at times felt like I was just checking things off a box), but lord did it get frustrating if you were trying to see everything.the plotline with Jude and his dad having a small timeframe to activate, with the game very very vaguely hinting at hit starting
While I certainly don't mind them making it easier, I always used to joke that you weren't playing a Tales game unless you were backtracking across the entire map with a guide every time a cutscene happened. I do sort of miss that feeling, though. The new ones basically telling me where almost everything is kills the exploration a bit for me. Not enough to stop playing the games though!
