Very fun game to watch, I hear a lot from pros mostly negative things regarding the Poles. So I looked at their tech tree, it seems pretty great imo. Bombard cannons, hussar with great upgrades and trample, great militia as you can see in video. I get it they are not great on water, or areas where you can't farm well but idk, they seem like a really cool civ overall.
I throw all videos on a 2nd monitor while I game myself. I like your matches vs multiple people, it helps me learn how to correct noob mistakes that you punish.
Spanish has been my favorite civ day 1.. if you get super nasty, you could control group micro 2 groups of conqs for near rapid fire shooting.. and going heavy farm with scouts as meat shields with onagers are very difficult to stop.. mounted monks shut down any elephant civ. The civ is phenomenonal
