One-point Xbox 360 Achievements have been done before, but they're rare. (Forza 2 has a pair.) If you play DJ Hero, prepare to gain a single point.
This is a warning or maybe it's a helpful hint for those striving for just one...more...point.
Me? I didn't notice until someone sent me a message over Xbox Live to remark that the DJ Hero developers had included a one-point Achievement.
You get it for playing your first mix of songs, which is the first thing you'll accomplish outside of the game's tutorial.
My gamerscore now ends in a one, not that I could even tell you what it is. Looking it up, it is...18,521.
I've got a request in to the DJ Hero developers to find out what they were thinking.
