The Another Century games
Officially, Growlanser 1, and Namco X Capcom - though Namco X Capcom has a fan translation, and Growlanser 1 has one in the works
I'd love for someone to release ACCURATE translations for the Trails series, and Valkyria Chronicles series, because the official translations are garbage.
An accurate translation for Final Fantasy VIII, because that official translation is garbage. Same with Final Fantasy Tactics, and Unicorn Overlord.
Accurate translations for the later Fire Emblem games, because those official translations are beyond garbage.
