ZZZ never recovered their launch numbers due to tvslop, but even according to the meme chart, their revenue is pretty stable after that. Wuwa is actually winning and recovered from their bad launch. Both games are also getting lots of improvements every new update.
Meanwhile, HSR 2nd anniv is making less than half of 1st anniv, and Cipher is looking to outflop Argenti. Story is getting worse, powercreep is still awful, no events, and barely any QoL improvements. You should be worried.
