I bet you're going to comment on 'Strife', aren't you?
I don't lie, so here's the explanation: I created this name when I was 9 because I needed to use a first/last name in a game. Ace came from my online alias, DAOWAce, while Strife came from, well, Cloud Strife, FF7, my favorite game. I'm about triple that age now, but the name stuck, and I've used it for any game which requires a surname. I don't prefer it, but hey, it's me, despite it uncommonly being copied.
