Wow, thats pretty awesome ! I never thought this would actually happen since the games are super text heavy and the prequel was never localized. Crazy times !
Heads up though ,you guys should definitly watch the orginal anime utawarerumono (not the one released recently) since this is a sequel at its core. The anime covers the psp game quite well imo, and you only need to know one detail that they didnt mention. After that you should be ready to dive into these games.
Nice, I'll watch the anime then to get ready for the sequels.
