There are some pretty interesting names out there, and I'm curious as to where the came from.
If it's the same name you use for all your online stuff, don't just say that. Say why.
If it's a name from something, say where and why you picked it.
I'll start:
James T. Kirk. Like from Star Trek. Into Darkness reminded me of how much I loved the original series, and I happened to see the movie right before I bought the game, so Kirk seemed like the best option.
I wish I could say something about how I (personally) identify with Kirk, how I'm some unorthodox problem solver and great leader, but it all started as a joke.
I got three of my friends to join in, and James T. Kirk, M. Scotty, Mr. Spock, and checkov ran around the Enterprise for a few weeks.
Like the story always seems to go, they've all faded away, but for whatever reason, I've stayed.
