He's clearly backpedaling from the minecraft thing. Remember, regardless of what he says about wanting to make things for the current fans, he's also been extremely explicit about trying to bring the gremlins into supporting him, so that they'll back his kickstarter or patreon or what have you. The Gremlin reaction was "Lol dumbass is giving up on the core concept" and then suddenly he's not doing any of that sandbox at all, and he's focusing entirely on the 10 rivals, which is totally what he was always gonna do. But he's worried that the Gremlins will point and laugh at how shit they are, and that'll become the gremlin perception of the main game.
Alex here thinks he's got it clever, being able to throw out any and all criticism about his rival experiments by segregating them into a whole separate mode. Of course, thats not how reality works at all, and the fundamental design failures in these new rivals will reflect what comes of the 'final' rivals, as Alex has shown repeatedly to not be able to learn from any of his design mistakes. All he's doing is wasting another couple years making shit thats not what he promised to deliver, to try and deflect criticism of it when he inevitably fails.
I genuinely wonder if its delusion or ignorance thats leading him to think he can just reconvince everyone who saw his shitty decisions the last seven years to suddenly come back and totally give him money. Is he deluded, avoiding the reality of the consequences of his actions? Or does he genuinely think he can just turn people around, as if the entire public perception of the project was just a score system he can increase with sufficient 'good' actions.
Alex, if you're reading this, and I bet you are, that's never going to work. At absolute BEST you could, with extreme effort, bring people from the "fuck no" camp, to the "Maybe I'll buy it on release" camp. The goodwill you burned that would convince people to publicly back the unfinished development is gone for good, its not a resource you can ever restore, for this project or any other. You've proven yourself untrustworthy with getting paid up front, and that stain will never go away. The best you can ever hope for is to convince them to give the finished product a fair shot.
You killed the golden goose, and you can't convince it to reanimate with good intentions.
