Dude, it's literally impossible made a low spec option for low end users, have a low spec machine, so low graphic card, low tier CPU, not much ram, etc. mean the machine can't handle the game, specially if you have low budget CPU and low budget ram, and why is simple, low tier components can't handle and can't process the same quantity of information, and even the less process they do, they do it slower comaperd to high end PC, so pretend to have a game able to work on low spec PC, means having important feature removed from the game, and well, that sucks, i obviusly know different country have different economy (i'm from italy, living in a city who risk one day yes and one day no, to become a ghost town, because the most important industry of the city, the one who litterally move the economy of the city, is with one foot on the grave so), and for the possible cross play with smartphone, until future news this is a rumor but, seems the cross play is only for the building mode.
