Not really. It just sounds like a grander name with personal value as opposed to say... "SmasherSamus". It is quite a mouthfull, though, so people might try to find a shortened version to call you by, probably Nirvana. From what I've experienced in online games, people almost always look for a shorter name to use, unless your name's already short like "Frown" or "Gigas" (<---Whoever would use that name is an idiot).
Now, I'm not trying to discourage the name, because it's a fine one. Just making sure you know what to expect from other people. You can also tell people to "CALL ME BY MY FULL NAME OR DIE.", and pull out a sharpened Wiimote on them. My first online name was "TemperBlade". People came to know me just as "Temp", which I actually became quite fond of. So when I try to make a name now, I try to come up with an easy... start(?) for people to call me by. For example, a new name I'm beginning to use is Gokkeisu. Odds are people are going to call me "Gokie" or "Gokkei", which is what I planned. I like to make an intimidating name, that yet has a short version for friends to call me by.
What would be wierd to me is if I heard "Buttwipe360" or "I_Suck" over the intercom.
Alright, so what names do you have in mind? What I would do is put down a couple names (if you have more than one), compare, combine, or divide to try to find something you like.
I would like to change my name too, but I've got too many people on my FL to notify, lol. I also don't want to lose my "Smash Lord" status. D= If I was a Mod, I'd probably change my name as frequently as my Avatar. Which means people'd probably erase me from their FL like 3 times a week before they realize it's me.
