I played it and uh... I didn't enjoy it very much. Enemies felt like they had way too much HP; your sword might as well be a foam pool noodle. The artes gauge filled up so fast that I spent most of my time just spamming special moves that were, in turn, no longer special. The CP system is obtuse. I found the characters personalities samey and annoying, constantly shouting over one another in battle and always finding the need to start a conversation about the latest doodad I plucked from a resource spawn point. Graphically, the game had a lot of non-subtle pop in, but the art design impressed me. The comic book style skits feel cheap though.
TLDR:
The graphics and battle system are worse than FF7R's.
The characters are less interesting than Dragon Quest 11's.
The skits are worse than previous Tales games.
I realize a lot of people who played the demo seemed to really enjoy it, and I seem to be in the minority. I'm actually happy about that, I really like the Tales Of games and would like to see them continue.
