The idea of day and night, perhaps even seasons, would be nice. But it would require all new graphics/backgrounds and coding to implement. And with so many International players, whose time zone is it set to? I appreciate the idea, many games (including war strategy games by Inno) already implement a day/night feature, many had night attack/defense bonuses or decreases associated with them. Many games did away with those night bonuses/decreases because of outcry from International players... when they were in day time and at work, their cities were in night mode, or vice versa, The same would be true here.
It would be a nice aesthetic addition. But let's get Inno to correct the existing game glitches and balancing issues and stuck quests, and new chapter features... before we ask them to "pretty it up".Also, it could cause an increase i the already heavy Memory usage for older CPU's and graphics cards... that issues seems to be fixed (for now). Let's not make it pop back up again. Having the game cause a crash and memory dump while you are in a battle really sucks eggs.
The idea of being able to rotate builds has been brought up many times, and dismissed many times. For good reason. If you can arrange any way you like change footprints... you remove a good bit of the strategy from the game. It is a City Builder Strategy game or so they claim (in spite of the overbearing emphasis on battle that keeps being increased sequentially...)
Just take your time, learn the game and read the wiki and the blogs for a few hundred different perspectives on the best strategy. Have fun, and if you don't like your city, you can always start over on a new world or start a new account on your existing world and try a new approach.
