If you played it in the past you might be interested to see that AOE2 community is doing great, and see one of the crazy players that are part of the community.

This particular player found a way to do absurd things with a unit no one else cares about.

The TLDR about the unit is compared to other castle age (age 3) units, it sucks. In age 2, it sucks compared to other age 2 units. It’s a unique unit (so only one civilization can make it) with weird mechanics, but considered worthless. It

It is unique in that it can be built in feudal age. But it has a very weird quirk where nothing in feudal age can do any noticeable harm to its castle age version, and as soon as you hit castle age, it gets its instant upgrade. Archers are considered the counter to infantry units, but they deal one damage a hit if the unit is in castle age.

So this player simply made a strategy that ignores everything else in the game to get a handful of these castle age guys to your base ASAP. Hilarity ensues.
