4 could probably use tightening up a bit. But I don't remember it being that bad. 3 needs doing though, no doubt about it, absolutely don't want that released with a 1:1 PS3 translation again, it'd be a complete waste of the remaster, as the whole point of it is to replace that butchered PS3 version. 5 seemed fine though, I don't remember any issues with the translation on that one when I played it through.
Battle theme wise... Kuze of course gets a shout, he's fab. Other great music is the final boss fight to Ishin (amazing), all of the For Faith remixes in 4, Majima's theme in 4, final boss theme in Kiwami 2 (specially the Kiwami 2 version, its remixed beautifully), and the entire soundtrack to Yakuza 3 (even its standard battle themes are insanely solid). Really it'd be a shorter task to name all the themes in Yakuza I don't like! (the series as a whole has a fantastic series of themes).
Anyway, back on Yakuza 3. Did the Komaki plot line yesterday and realised that you unlock his moves super early in 3. So Kiryu is now kinda powerful. The enemies are no slough in 3 (much to my delight) so having powerful counters helps out loads.
Also did some batting cage stuff. Still don't understand why the hard cage is actually easier to S rank compared to easy or medium in terms of point requirements. I still have EX Hard to go though,. That'll be... fun.
