They’re not something I go for very often, or that I see other players use very often. But I really think the ability to get units like Royal Knights as the Byzantines by putting a Mercenary House near a neutral Trade Post gives some fantastic flexibility and powerful units, at the cost of needing to ensure you have control of your supply lines since you can’t build wherever you want.
It is a sleeper because it is the least reliable mechanic in the game all due to some quirky developer thinking this is candy crush. I don’t want to be harsh on these guys, but RNG like this is incomprehensible in a competitive RTS.
It’s very hard to take you seriously when you make a ridiculous claim like “this is candy crush”.
But I’ll do my best to respond as though it were a serious comment by a serious person, rather than the trollish bs it seems on the surface.
Yes, which units you have access to depends on a random spawn. It’s just another thing to scout, like finding sheep, finding secondary gold mines, or finding good places to wall off. Like with any of those things, you adapt your game plan around what you find.
In my recent game where an opponent was going heavy into M@A, I knew I’d benefit a lot from taking advantage of the Royal Knights in the back of my base. Arbalétrier might have been good too. Or if I had no good trade post mercenaries, crossbows and Varangians. Or Landsknecht or Streltzy, through the Western Contract. Trade Post Mercenaries are an added bonus option you can take, if you scout and adapt. It’s never something you need to have, which would indeed be bad design.
