I've won a couple games in my time, so I will share a more generic story. My favorite wins were always the ones where I was facing a large team that was trash talking me because I was running from them. I can think of three stories off of the top of my head. The first one was on SG4, I was on top of the fire station/car wash protecting myself from a team of three. One of the three was calling me something offensive, I can't quite remember what but all I remember is that I knocked them all to their deaths.
The second one occurred on TSG2, there was a stacked team of 4, wearing full iron and iron swords for the most part. I was in the water by the steamship so I evaded them for a while with my fishing rod until two of them eventually left. I saw my opportunity and I killed a couple of them and finished off the team.
The last one was on Breeze Island, there were four players alive including myself and three baccas. Admittedly this was a bit of a cheap win, back when sponsoring was pretty over-powered. A friend of mine sponsored me a couple items, one of them was a poison bottle and the other an invisibility. I ran into the water and threw the poison bottle at one of the three baccas, this drained his life to half a heart so I shot an arrow at him and killed him. The other two I took down in deathmatch using the invisibility.
I know the stories are a little shaky, you have to take in mind that they come from a long time ago, my memory of them is a little foggy.
