Got the email as we were visiting my parents this weekend. Still ran pretty well on my parent's machine (should have since i built it, lol); Well, once it finally stopped getting stuck on the server (I guess) and actually loaded the game. Ran fine today though. Comparing it to the older versions, I like it so far. It is great being able to zoom in so closely, and how doing things that should work actually do work (always had issue with water and electricity working in 3000.) Having said that, I worry that this game will be too easy to excel in, which could possibly take away from the strategy of it all, but only the full game release will say if that is a valid concern.
