The thing with Shiftup is that they are already successful at doing GaaS Gatcha. But the heads of the company clearly look upon that business model as a necessary evil and wants to go 'legit".
Stellar Blade would make much less money for more effort than past Gatcha games. But the studio might be aiming for greater things than loot boxes.
There are many games in Asia that would otherwise be great games on their own, but because their financial plan was loot boxes and slot machines what could have been a great game would get buried by the gatcha mechanics. i don't know how long Shiftup can keep this up, but I hope their dream of being a legit studio that doesn't require them to exploit their customers , bare even more fruit in the future.
