I was going to post this in my other post, but forgot it.
Another thing the description in the first link really reminded me off was fighting IRL (not brawling or streetfighting or anything like that). The way it was described was so much like that, seizing up ones opponent, checking out their weaponry and going over probable scenarios in ones head. I've yet to come across that feeling, for real in a game. Some games have some of it, but when you have the real deal to compare it to, it doesn't even come close.
I remember one such fight I had, at a LARP (and before you come with all your prejudice and stuff, this was a real LARP, not one of those American or German atrocoties you can find on youtube). I was a little overly cocky against the captain of the guard in a village, when they were drilling, and he threatened me, he said "maybe we should use YOU as target practice". Of course I agreed, thinking he would get in trouble if actually tried something, but he drew his sword. Starting to panic a bit I draw mine as well, this guy is bigger than me, older than, wears a chainmail and looks pretty experienced. He turns around and begins to walk away, and I he came to his senses, not wanting to start a fight, but instead he walks and picks up a shield. He now has an additional advantage over me. He is on level ground as well, while I'm standing on a rock surrounded by a trench. I draw my dagger in my offhand just to have something to counter the shield with, and he comments about it, then starts advancing. Realising that I can't hold my ground because of the bad balance I have there, I jump forward as fast as I can against him, thinking to get behind him and down on ground, and slash against his legs. He didn't have time to react, not with the shield to block or even to strike against me despite my vulnerable, extended position, so I jumped back again as fast as I could. "You're a fast one, I'll give you that." And now he looks even more prepared, albeit limping a bit, he takes on a lower stance, and faces my new position. In my head I try to find some way out of it, I can't kill him, then I'd get killed, most likely, or thrown in jail. He's captain of the guard after all. And I can't talk him out of it, he looks quite into it now. Just as he's about to strike, a higher ranking officer shouts at us, breaking up the fight. As he gives the captain a lecture, loudly, about his behaviour I sheate my weapons and slink away, with a sigh of relief and a short salute. That was a close one.
The fact that I was there to stake out the mayors housing for an assasination attempt made it even scarier. What if they caught me and found out who I was?
