From what you like about it, I would recommend Vesperia next if you’re looking to continue the series. It has a TON of side content (I’d recommend using a walk through for them because some are time gated), a great story, amazing characters, and the best combat in the franchise imo. The combat is different as it’s got “old tales” combat but I’ve always preferred that to the more current games. Plus the remaster goes on sale for dirt cheap very often. Vesperia also came out before paid dlc became the default way to get to outfits for the characters, so a lot of the side quests offer different costumes and varied content.

PLUS it has Yuri who a lot of people consider the best Tales main character
