I love Tales games, but this has been one of the most disappointing games I've ever played. It has a really interesting concept and I like all the characters in the main crew, but the game play is atrocious. The enemies feel horrible unbalanced with normal fights being way too easy, and bosses being way too hard.

The combat system has on a mechanic to make hitting enemies easier, but you refill your gauge by hitting said enemies. So for a while you just can't fight properly.

Go play Tales of Berseria instead.

Before getting into details, I'm giving this game an 8.7/10 overall

I'm a long time fan of the Tales series, all the way back to Tales of Phantasia and this game lives up to what fans would want from the next installment.
First and foremost, the visuals for this game are astounding, especially the combat sequences and abilities you have at your disposal. If that's a big factor in what you're after in an jRPG you won't be disappointed.
I enjoyed the overall story, but there are some holes in the plot that can't be overlooked. Despite that, I was still invested in seeing it through and the pay-off was satisfactory. It's not stellar by any means, but I didn't finish the game with any lingering negative feelings towards how things wrapped up. They also could've put in more effort in how/what they named locations and enemies as most of them are easy to forget due to how obtuse they sound.
The combat itself is incredibly fun, and if you've played other Tales games in the past you'll kind of know what to look forward to. It's real time combat with a party of 4, and un-used party members can be swapped in midfight if needed but more importantly you can still benefit from some of their abilities by tagging them in for a Boost Attack or Boost Strike. I do wish there was more variety in the pool of enemy types since there is a point in the game where you'll immediately notice them re-using reskinned versions of ones you've already seen.

My biggest gripe doesn't have to do with anything mentioned above, but it's in regard to pay for power through DLC purchases. You can get permanent boosts to exp gain, SP gain, much cheaper vendor prices, free level boosts, cosmetics, but most egregious of all --> every character can gain 3 additional Skill clusters. You can make it though the game without these skills, but they are definitely noticeable power spikes. Most notably is Dohalim's Fairy Circle ability that he gets from one of them, which is the only AoE healing skill he has that's pay-walled. This skill alone could make him a viable solo healer, and with access to it you can even double up on healers in your party making staying alive SIGNIFICANTLY easier.
