It was late 2008 when I got my PS3, which would have made me 26. My normal online name Triggerhappytel was taken, so I reverted to my backup name Telminator, which was also taken. Bastards! I don't generally like names with numbers in, but Telminator-2 was available so I went with that, and I don't mind the numeral as it's kind of a spin on one of my favourite films.
I'd definitely like the option to change it though. Would pay a few pounds for the privilege.
