Wow :P you gonna start blogging actively now.

Usually, these games work in a way that people who joined early have a huge advantage against others. If they buy an exclusive item, they can sell it later for a greater price.
With this in mind, everyone just try to get early on these projects to get limited edition items.
But everything is ok at that point, until the developers decide to just shut down out of nowhere. It's ridiculous how many projects are creating whitepapers and asking people to buy an advance subscription or item to fund the development.

Anyways what happen to not generalize :P. To be fair I think all or most projects have early access stuff to give benefits to the people that were willing to take the risk. As you said, there project are projects that could have failed or rugpulled. It could be worth less in the end. If rugpull, I think it's our fault for not researching enough about that project. Even non web3 games you may see kickstarter stuff and they do give lots of extras and benefits who gave money for the project early to have funds. I don't see this as a scam. Anyways I don't see anything wrong with this stuff. I'm just against inside trading or the people that develop the game to hold assets in the game they very well make decisions which could have economic impacts toward in game assets. I don't have time to go thru your other points but I will just leave this here
