My in game name is Reece.
The name Reece derived from the name Rhys (they are both pronounced the same), and the name Rhys originated in whales.
Then one day something great happened, I was born. When I was born my Mother decided to name me Reece (good choice) and that's the story to how I got my real name.
When I was installing windows into my new system it asked for a account name, so I went with Reece (good choice).
Now, one day when I was in the process of making a steam account, I saw that alot of my friends made a alias (so not there real name) for there steam account, now I asked them why and there response was "because it's an awesome alias" so when I finally decided to make my alias I just thought of something awesome, so of course I had to chose the alias Reece (good choice).
When it comes to my Arma 3 alias, well I didn't have a choice any way because arma decides to name your first profile after the name of your windows account, so it was Reece (Arma 3 made a good choice that day).
And that is where my in game name comes from.
