I know. It just sort of pisses me off when I hear a JRPG fan (not directly referring to Lynx_7 but speaking in general) not being open-minded about a damn JRPG. Not everything appeals to me either but I can acknowledge that just because it doesn't appeal to me... doesn't mean its not high in quality. Too many people (who claimed to be SMT and Fire Emblem fans) walked away from TMS without even trying it for themselves and it's a shame. Hell, you know the same thing is happening to Persona 5. "It looks tooo anime!!!!" It's annoying as hell.
Except the post you responded to said he figured it was good quality. They're saying it bombed (which it did) and said that the premise of the game likely contributed to that.
Most people into idol games are likely those on playstation platforms. The game still comes off as not really having elements that appeal to those interested in either franchise which impressions also seem to give off even if it stands on its own. There also doesn't seem to be attempts to make it more WiiU audience friendly like Splatoon which despite being a shooter has a lot of appeal to the Nintendo audience.
This makes it seem like an idol game that doesn't take advantage of being a crossover by having what fans of either franchise likes that also doesn't make any strides to appeal to the more wide WiiU audience. This doesn't mean it isn't good. It just means that it doesn't do much to attract potential customers.
