I was debating on whether or not to watch the anime. I tried the game, but that kind of combat isn't fun for me. I did think it was more fujo based on the two MCs interaction (the male MC and the spirit(?) that is). I liked how the story started but the gameplay was too much for me, so I may end up watching the anime. Plus it's Ufotable, their animations are gorgeous.
I actually think it's better to watch the anime without much knowledge or attachment to the game, since the anime breaks a lot of the rules the game establishes so a lot of tales fans (on tumblr at least) hate the anime. It breaks so much rules and diverges so far from the events of the game; although I don't think that's necessarily a bad thing. Ufotable already had a lot of materials in the game to work with for both pairings so it's not exactly out of nowhere. It's just surprising they amped it up to that extent. They were pushing that border between subtext and outright confirmation pretty hard in that finale.
ufotable definitely brought their A game for this anime in terms of visuals at least. It's especially obvious here too since each seraphim (or spirit as you called them) has their own element so they can actually show off a bunch of special effects. It also has 3D dragons.
Anyways, since this is dynasty after all, I have to mention that yuri wise there's the redhead + her blonde princess that takes matters into her own hands. Hm, kind of sounds familiar. Main character paired up with his childhood best friend is very sweet too.
