to be fair, these days a game needs to be monetized as fuck, you can't just drop it and live of the box sales (unless you get very lucky). and that's before you consider what engine your game is supposed to use so it can be modded, while being able to run and look AAA on last gen consoles AND make them happy that your game won't be used to fuck with their walled garden.
valve can just drop a game into the open and not care how much people do with it, they make their money elsewhere (but even then they culled artifact).
the smart play of TRS would've been to piggyback off a known brand the same way fatshart does with warhammer, then you can sell whatever because you got enough retarded consoomers lapping it up.
