I agree that the game is more simplified, I think that was a goal from the beginning. The game plays very fast, no menus or screens to look at each turn, just a handy to-do-list that steps you through all that requires your attention that turn. This isn't my favorite part of the game either, but the designers did accomplish what they set out to do, which I feel was to make a game to attract new people to the franchize.
Complexity can be added latter, and it will be by the modding community. The specialists, religion and health will all likely make a return after the modding community gets some time with it. It would be very hard to release a game that is both more inviting to new players and also more complex and challenging for vets who have played CIV for 17 years in my case or more.
For now I'm just enjoying a very brisk game where turns speed by and I don't have to remember to check anything, because there is nothing to check and the game reminds me to do everything. I could see some sort of i-phone app to run this game, epecially if you are a builder type.
