Ok, but you have to admit the idea of connecting all these achievements to a single profile is something that nobody had done before.
Microsoft is probably the first constructor / publisher to link game feats to user accounts for all games. It's were it stops being a invention but rather starts being a refinement (still good if you like achievement):
- I had already a number of achievements linked to me: the Hi-Score table of arcade games was the off-line version. Of course, the profile is limited (just the same three letters), but in a arcade room, when someone is trying to beat your score, you can say: "Yep, 'ZOZ' is me. Good luck, kid."
- A number of games allowed players to publish their scores, timing, etc. on-line, on the editor website.
- There was competitions based on achieving a particular feat, recording it (via a camera), and winners got listed and got prices. Magazines, forums, had sections dedicated to that - like the Nintendo owned magazine.
I'm not really receptive toward MS game network: my last tries to make a X-Box Live account resulted in an unexplained numbered error, and my last experience with the PC version of Live (for Fallout 3+) was awful - not to say Sony or Nintendo are any better: I hate the slowness of the Sony network (and this thing pushes mandatory updates to play any game), and the Wii store interface is unresponsive, to be polite.
