What is “REX” or “REXing”?
REX stands for Rapid Expansion. This is a strategy some people use in the beginning turns of a game: the goal is to basically expand as fast as possible, claiming as much territory as you can (as more territory usually equals more power), even at the expense of military and defense sometimes. This involves building a granary early on to promote growth, and then literally pumping out settlers and workers, with few military units for city defense. Once all land available has been taken up, then you can resume normal production of other units. This strategy works most of the time, although you should always be wary of the AI if they have any units lurking around!
