Swordfighting is awesome! I wonder if who will win Samurais or Knights

Yes it is!

Good question. I would say that the knight has a slight advantage in that his armor would have much closer gaps and would be used to a variety of combat systems, given that he would have been in battle against soldiers in other nations in multiple occasions. Samurai armor tended to have somewhat larger gaps, since they didn't really have any thin weapons to speak of. And also, given that the Japanese live on a fairly secluded island, they would have had a very inbred combat system. Their ways of fighting would have been developed with only their ways of fighting in mind, and not, say, the Chinese or the Mongols' ways of combat.

Samurais used Martial Arts while sword fighting. If only you know For Honor. My favorite warrior is Nobushi and my favorite weapon is the Naginata, Nodachi, Kanabo, the Flail, and theExcalibur

So did knights. They utilized punches (quite effective with gauntlets!), grappling, and joint dislocations frequently. I recommend you read The Flower of Battle, by Fiore Dei Liberi, if you want to learn more.

Just so you're aware, video games don't usually reflect reality that well.

I also like actual Martial Arts like Muay Thai, MMA, Taekwondo (I'm a yellow belt), BJJ, CQC

MMA, Italian grappling, and Glima (Nordic wrestling) are more my taste. That way, I have some ground game, as well as upright combat. Not judging your selection, however; each martial art has it's own place of usage.

I love McGregor so much! My favorite about him that he used the Meia Lua Kick from the Brazillian Martial Arts Capoeira. If only you heard Eskrima (Filipino Martial Arts that used sticks to fight) You join this if you want https://imgflip.com/m/MartialArts

Admittedly, I don't actually watch MMA fights. I just somewhat study the art itself. I'm much more focused on Italian grappling and Glima.

I actually have heard of it! I don't know much about it, but I hope it's better than their knife defense system 🙃

'ight, I just followed.

Thanks! I also do Martial Art Breakdowns in Movies like Ip Man and Undisputed.

Vikings are deadly warriors because of Glima and they can also do charging takedowns as well. I watch a Glima fighting video. It's so awesome the Single leg and double leg takedown and almost related to Greek or Roman Wrestling but has takedowns

Yes, they were. That's why I'm studying it, in case I get in a self-defense situation.

I wouldn't be surprised at all if it was inspired or influenced by Greco-Roman wrestling.
