Speaking of games with the abbreviation TH, I finished one of the routes in Three Hopes.
It wasn't bad. I actually liked most of what was there, even. The exclusions are really strange, though. Byleth didn't end up playing that much of a part and the brief detour to dubstep snake people backstory before the game goes "Anyways," and the ends on a cliffhanger was an... Interesting creative choice. Dimitri was a much less interesting character when he wasn't a hulking ragebeast.
Shez was a fun character, and Byleth is a much better character when she isn't completely mute, go figure.
For a spinoff that was made to distract people between houses and engage it wasn't bad by any means, but it's a shame they didn't go a little farther with it.
