Hello, I am new to the civilization series
,never bought it, but I have read about it for a while now. I finally decided to take a chance and buy the gold edition(Still don't have BTS) yesterday. I am throughly enjoying the game, but I am not very good yet.
I like to war but I am having a hard time finding a reason to do so, and having trouble getting the other leaders to help me in my struggles. I also have a hard time taking fortified cities. Can I get some help, and maybe some other general tips?
Edit: Also, what does REX stand for, and how does it work?
