Shadowverse

The downsides of the Japanese version:

- The awful voices of Yunie and the bell-ringing angel.

I have a neutral opinion about the angel (although I'm not a fan), but Yunie also doesn't appeal to me. However, it's worth noting that she fits the image quite well.

- It's hard to understand anything.

There's that satisfying feeling when, thanks to years of watching anime with subtitles, you can understand a good portion of the characters' lines. It also helped that my sister studied Japanese at university, and as a true anime fan, she enjoyed mixing normal speech with insertions of some anime-related words 20 times a day. Whether I wanted it or not, my dad now understands a small part of the vocabulary in Japanese.

By the way, regarding any dubbing in general, I always prefer to play with the original version, which best conveys the spirit of the game as planned by its developers. And if there are also subtitles with a translation, that's a 10/10.
