The game is turn based, and you can take as much time as you like for each turn.
Some of us take days for a single turn. Some others complete a game in a day.
There are 540 turns in a standard game, at 2050 you are in turn 541.
The fact that you reach this turn in a mere hour doesn't matter.
Except that maybe, you could take more time thinking about your strategic decisions each turn? It will help you build your space ship before turn 540!
It helps to turn on the feature "always wait at the end of the turn" in the preferences screen. This way, you always have to manually click the "next turn" button when you are done with a turn. This will allows you to fiddle around with all kinds of things in your game, such as what cities are building, or what your slider % are set at.
Yes, ALWAYS wait at end of turn, I thought I had it turned on (but didn't and had many many many moves ruined, simply because the turn would end. I thought the option was broken, so I would always un-fortify some unit and make them wait until they were the only one who hadn't moved.
I think y finishing a game in a mere hour he means conquest or something, not 540 turns. That would be difficult (at least for me).
Edit: Someone mentioned something about saving the city's queue, I could really use that about now...
Also, I have been building cities CxxC mainly because I don't need to fill the gaps in-between. I would like to switch to CxxxC because:
1. Still no need to fill gaps.
2. The one-move-from-city-to-city thing isn't that bug of a deal for me. I rarely make use of it.
3. I REALLY need those super-high production cities later in the game, when I can finally build wonders I need to build them FAST. Of course captured enemy cities could be used for this, but generally they are still building basic improvements (temple, courthouse, harbor, market) when I need them to start building wonders, plus they have low population.
Any thoughts?
