I would vote yes if this was an exclusive sim city project that also allowed connectivity to a sims game. i've actually wished for it over the years.
but for this to be functionality add to the sims, nope sorry, and i'm not willing to sacrifice my graphics. i will admit, the sims 4 is the best looking sims game thus far, but i dont think the graphics in this game are so amazing for current gen gaming. and definitely not willing to see them watered down any further.
I would definitely not want to see a sims / sim city crossover if it affected the sims timeline of releases whether that be DLC or a new addition to the series such as let's say a sims 5. so being that sim city is no longer a thing development wise, i have to say no.
