I can understand the tagline will attract people to the game, most of my issue did come down to that.
I think the issue at hand is that if life worked like a video game, then everyone probably would be happy and everything would just work.
The reason the soviet union was able to function at all was that they imprisoned all the unhappy people, which is the other side of that coin. Capitalism has been effective up until this point because of how it's removed democracy from the economy, the people at the top have the power and we've seen the violent effects of that, but real life people also have things to lose, even if they want to rise up and chop heads off, there's a lot of resistance in the status quo.
Maybe you need some sort of buffer to simulate how poverty works in western capitalist systems, people have enough resources to not die from a lack of food and water, but maybe poverty just decreases their quality of life compared to others, and societal collapse only comes from real food shortages and other aspects.
