Some thoughts: I know Minecraft and Minecraft-esque are extremely popular, and when you publish a review on such a game's page, you're talking to these people. But I'd have liked some more talk assuming I don't actually know those games.
I'd have also liked some more thoughts in general.
Anyway, here are my thoughts of the game as depicted from you: My first reaction was, "If a game asks you to run it for 160 hours just to passively farm, that's terrible," and then I saw about the 30 real life days, and I was like "neat!"
But then I went back to not liking it. Let's say it's for people who actually spend 30 real time days playing it. That's crazy. That's 720 hours of game-time. For many of my older friends, even a game like Persona 4/5 with its "full game experience" of 100-120 hours is insane. And you want 7 times that? No way.
So let's look at the thought of letting it run idle, because time doesn't advance as you play - talk about ironic, as you're using up real world resources and creating heat and pollution for no real gain, if you could've just had an option to make time skip ahead by 4/8 hour chunks, say, to simulate the player sleeping or going to work...
Also, about the price of gas. Most environmentalist-oriented economists will tell you that gas is underpriced, heavily. That is to say, it's priced so low because the economy will collapse if it were fairly priced, while taking into consideration its limited availability.
