I was playing a game recently where I ended up with many, many slave workers later in the game. I'm sure this is extremely common. Anyway, I found it tedious to move every one of them individually and since it took several workers per square to build a road or mine, etc. I had an idea. What if there was a way to create a unit similar to an army called a "chain gang?" This unit would hold 6 or 8 slaves in it and they'd all move together as an army does and work as one group. Therefore, if it took 6 individual slave workers to build a road on one square per turn, the chain gang could build the same road in the same amount of time, but would only require you to move one unit and give it one command instead of moving 6 individual slaves. Does this make sense? I thought it might be interesting to try this. Does anyone like this idea, or am I crazy?
