Just beat Lord Gwyn for the first time. I dont know what it is, but for some reason i was getting really sentimental during the fight. I was kinda reflecting on all my triumphs and losses, the struggle it took to get to this final boss fight, and now it was all about to end in a stunning climax. Maybe i'm just being a big nerd and such, but think it was actually moving and it really effected me.
Or maybe it was just the music.
