Stellar Blade doesn't need to be memorable, it needs to make a profit. 

Shift Up might be new to the triple A game scene, but they already have a mobile game (Nikke, Goddess of Victory) that's pretty much just a machine that prints money for them. They've built up a good reputation by being open to player feedback and giving them what they want. I'm not a huge fan of companies going on the open market, but (i'm told, but cant verify) the CEO holds almost half the company's shares and his wife is holding a bit of it too, so there shouldn't be a drastic change in the company's vision for the foreseeable future. 

Thanks to the culture war, Stellar Blade is going to be a guaranteed success so long as it doesn't release as a half baked mess. Too many people are talking about it, and all that talk generates interest. There's even a demo out, and apparently it's good. I'm not sure where the Neir comments are coming from, nor have I heard this take anywhere but here. Yoko Taro said they were enthusiastic about the game, but that's because he's never been one to hide the fact that he likes sexy woman in games. 

I don't really have a pony in this race. I don't have a play station, nor would I be in a rush to buy a brand new game given that 99.9% of them aren't truly finished until at least five years after release. Even if Stellar Blade bucked that trend and eventually got ported to steam, I can't say I'd rush out and buy it. It's not something I would normally play. But I'm fine with it existing in the video game ecosystem in what is sure to be a springboard for bigger and better projects from Shift Up. 

Regardless of how Stellar Blade performs, I feel like it's not going to have a huge impact on the culture war. At this point, it feels like something that's going to go on forever so long as people continue perpetuating it. Both sides are dumb. Just stop talking about it.

Also anyone who doesn't like Inscryption probably doesn't like card games in general and should stop spreading their wrong opinions on the internet post hate.
