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?
