Years ago I found this huge list of the most popular royalty free/custom soundtracks, many of them also being from what 2ch and nico nico consider some of the most most popular, classic rpgm and doujin game titles.
About roughly half the rpgm games games on this list are already translated but I think it's worth taking a look into what could be more potentially cult classics that may have been over looked.
‚3‚¢‚Í‚ÄHOSPITAL, Knight Night, BREAKER, PIERROT+, Divided Girl and Almagest -Overture- really seem worth translating IMHO.
