In Civ5, when you have access to iron, does it make sense to build musketmen?
Technology upgrade tree looks like this:
|Steel | |Gunpowder | |- Longswordman | |- Musketman | | cost 150 | | cost 120 | | str: 18 | => | str: 16 | | mov: 2 | | mov: 2 | | req: steel | | req: - |
Therefore, at first glance I thought that since the Musketman is a unit for a later technology it would be "better". But it appears that as long as I can build longswordmen and have the time to build them, I should not spend maintenance on musketmen.
Am I correct? What about upgrade paths?
As shown in this question the upgrade paths are the same. So I guess it comes down to whether you are willing to wait the extra production time, and whether you have a better use for that iron. Besides building other units with it, keep in mind that you can also trade it to a friend temporarily for an economic boost.
The other factor is that if you are under attack and you lose some sources of iron, you could start suffering a penalty to combat power if you go negative, which is less likely if you stick with the musketmen.
