Actually, this is as good an opportunity as ever. Unlike @Julius there, I have played a job-based RPG. You clearly wouldn't know, Mr. Imposter, being new here, don't worry, I'll drop that joke now but I looooooove job-based RPG's.
Is Yakuza 7 a kind of Final Fantasy 3 deal, where the jobs are entirely seperate and have no real benefit if you level up a job and then use a different job? Or is it more like Bravely Default, where leveling up a job gets you passive benefits that you can equip and use on other jobs?
