I changed it because I had Bloodex (or some variation of it) for about 5 years. I wanted something new, and for a while, too, honestly. =P I changed it to Vertigo on a whim, though. Honestly, I'd spent a lot of time thinking of a good new username, and came up with a few. The good ones were taken though. And then I remembered a random memory of me playing Resident Evil 4 and fighting a boss in that game called "the right hand". Back when I first played it, I remember someone telling me that the boss was known as Vertigo, something I figured out recently was never official. That memory popped back when I was looking for a new username, and viola. I just found myself a sexy username. =D
