The game is returning but as a remake as thirtyseven is not returning for now dw some characters will remain the same others will be different as some assets are thirtysevens
When you're talking about characters being the same/different based on assets belonging to ThirtySeven, I assume you mean the character models might change? Because as far as I'm concerned, as long as their personalities remain unchanged (mostly, maybe a couple tiny tweaks here and there could be beneficial) and their looks are generally in the same ballpark aesthetically, I don't think it'll be a huge deal.
