Of these, I've only played Half Earth Socialism: the game. I really loved this game. It's a little basic, and it can sometimes feel a little broken, but it's fun and educational. As alxd notes, a lot of the games are well-intended, but mechanistically incompatible with their themes. That's an issue I've definitely observed as well.
I like to see that more folks are trying, though. I don't expect any of us to get it completely right, but progress is progress. With more entrants, I expect the average quality to continue to rise.
