Sounds really nice when you put everything like that, but how can you say that this is not scam if since last june of 2021 they only release two parts of Pre-tech "major" update and if you check out the change log there is only six "new" things added so they "worked" from march 2021 on only six noticeable changes for 70k monthly, how in the world can you defend that? There is no way we can justify this scam man, I can name to you other devs that provide monthly and weekly updates that deserve more support than people that starts doing this, we as a community should not stand this kind of treatment...
Then go support those developers and unfollow this game. I do not understand the entitlement shown by people getting games for free on here.
The game is free for anyone to play while it is in development. If you don't like it - wait until it is complete to play it.
Yes, there are patreons giving money to support the developer. But 99.99% of the players are not. What is the scam? If they didn't want to give the developer money, they don't have to. As part of their donation, they get to vote on future content polls (which the developer does take notice) as well as other perks they see worth their buck. When they feel like it's no longer worthwhile, they will stop. It's their choice.
When you walk down the street and a violinist is playing with their case on the ground - you have no obligation to put a dollar into the case. You can listen for free for as long as you want - even if the violinist only plays the same song over and over and over again. There will be people who do toss a dollar in because they appreciate the diversion, the music, the way the violist holds their bow, whatever. They could drop a dollar daily. It's their choice.
Either way, you're getting the entertainment for free. Everyone knows what they are getting into.
