That would be ridiculous. The name itself not matching the child's ethnicity is bad enough, but being named after a video game character would be pretty embarassing as well. --- http://www.xboxgamertag.com/gamercard/lRushdown/fullnxe/card.png
I really try not to consider ethnicity, but thank you for your opinion. As far a naming after a game goes. I really don't see the problem in it. The name has more meaning behind it than that. Look it up.
You don't consider ethnicity? Well I hope your kid and his schoolmates are understanding. If you're white, you should also Mustafa and Shaniqua lol --- http://www.xboxgamertag.com/gamercard/lRushdown/fullnxe/card.png
With an English last name, Altair would sound weird. It's a unique name, and it will make him stand out in a bad way. Expect him to get picked on regularly. If you're ok with this, then go right ahead.
