To be honest, I spent $80 bucks on the deluxe version and was extremely upset for a few months. My cities would be working great then just completely break down due to the problems they had with map interaction and trading system that was set up. The Arcology worked horribly causing huge traffic back ups.
I recently updated a few days ago, logged in to my old cities and they are working much better. The game seems much more finely tuned and I will continue to play. It is classic EA to release a game way too early and work out the bugs on their actual customer base.
Can't really blame them, we all keep buying their products so we can only blame ourselves. Overall I'm happy with the end product now, DRM never mattered to me because my connection is always online and I prefer to play with friends anyway. The problem is now just getting friends to come back to the game now that it is working correctly.
