I don't think it is going to "fail" but I think the drop off rate is def going to increase.
With most players, this game just became on of those $$$$$$$$$$$ holes mostly for fashion, but there is a lot of content exclusives for this, and I mean NA added the mission pass that JP never had.
MY biggest concern with all this is the amount of content.
Not because of lack but because of excessive. The amount of content that is being released and the manner it is being released to catch up to the amount of content for a game that was released back in 2012. If you actually go into the catalogs of what items where released in Jp you will see hundreds of items both exclusive partnerships with anime's/other games and you can see that most of this will NOT come out here "fully" as some members have noticed some items from these anime's/game/ content releases split in mission passes, fresh find shops, scratch offs, and even ac shops, not to mention those extra exclusive offers, or SJ/AC bundles.
The amount of content then makes people go crazy buying everything, prices rise for "popular" items but Meseta being primary easier for those already with premium. There feels more of a grind then enjoying the game for some vs others. But most games are like this, other people just stopped caring and play the game for nostalgia vibes and also because the base game is enjoyable. But the clear separation is a bit annoying. Plus the missing content or even game play mechanics/alliance options for a game that should have had all this down before release. I mean it's not like it just came out. So definitely other people who where playing feel like been there and done that, but we feel this is their last cash grab before they decided to release an actual new game because of the success of this. But they will milk this for as much as they can because they infidelity have those people who will spend that kind of money and use the excuse of enjoyment over content, which is perfectly just for them. It is THEIR money and their enjoyment.
It's a fun game, the company is doing what looks like their best,, and the enjoyment is there as long as you don't mind losing out of toooooooooooooons of content because of how disgusting the market is. Plus honestly I rather have these people playing inside then going out and making my work more difficult. Still I am glad I was able to snatch the Lab coat though I already had a scientist setup.
Still no game is forever....so far forever still hasn't ended.
Still I am not defending the game or the players, but yes I don't think the bad things they do will effect the player base, if a game is toxic the smarter/weaker people will leave, those who stay are either immune or toxic themselves. All games are like this. Everyone is fair game, veterans, newbies, it doesn't matter. Here is hoping things get better, maybe they add that meseta mission weekly, maybe they add catalogs for missing content that can be bought at any time, maybe they add ac free scratch off for high level missions drop chances. Who knows and who really cares tbh.
