One thing I will say is that this so far has NAILED the experience I remember of loading the game. Thinking the PC had frozen, only to finally be greeted with that gorgeous Maxis loading screen and opening animation.
I have not yet determined if the sim speed goes nutso on Cheetah like I remember, but I will edit this when I do.
Coming back to edit and say that this is absolutely unusable, either due to demand or underspecced VMs. I cannot get through laying infrastructure without the entire emulation freezing hard and forcing me to reload the page.
Coming back again to report that I have been trying for an hour and a half to just get past the city creation stage of the game. I can only get to the point of laying infrastructure in 1/10 attempts and I lose all progress every time because I can't save before it crashes. This is woefully underpowered for a simple simulation game, I c a n n o t i m a g i n e h o w s l o w i t i s f o r a n y f p s o r r a c i n g g a m e.
