Wow no regards to spoilers at all you just blatantly open up with a key point of episode 4. As a JPN player I'd rather people find these things out on their own accord since the pay off at the end is worth it.
this "key plot" is pretty much spoiled in the shopping area and trailer, so not a spoiler.
Also nothing you brought up challenges the idea that they are the ones that brought politics into the mix with their choices. I listed why other games avoid this sort of landmine and asian doesn't account for anything when the top MMO WoW isn't asian at all and many other games like Guild Wars, ESO, Runescape, SWTOR, etc.. again aren't Asian.
My point is that its speculative(why those MMO's don't do it), do you have proof of this? As to those games you listed, I stated why. lore reasons(Which this game and PSO in general isn't consistent with). Also this game isn't even a MMO technically and on top of this many Massively Globaly played games like League, Fortnite, Paladins, Overwatch and smite does this. Doesn't seem to be a political outlash there, so this American symbolism bringing huge issues into the community doesn't hold water when you take that into account
Also episode 4 doesn't break the fourth wall it sounds like you need to play through all of it.
lol of course it doesnt....
Again they injected politics into the mix the reasoning doesn't matter so the toxicity of poltitical discourse hitting the game is an obvious outcome that could have been easily avoiding by merely looking at the history of those that came prior.
Many have already addressed this, so I am not even going to dive further into it...Btw there is no actual outcry hitting the game, its literally 1 guy.
