Achievement system

I would love to see a reward system based on your total gamerscore, not sure what they could give you though as rewards...

Some kind of global ranking system would be nice, I know True Achievements is there but that only shows people that register on the website, whereas Microsoft have the real data to hand.

The achievement system is great and I like the idea of grouping them that someone brought up. I would also like to see you be able to brag about specific achievements in your profile like Ubisoft does with their badges. Avatar rewards would be great
too for completion achievements. What is wrong with advertising for the game with a shirt or hat after you spent hours completing the story?

I'd like to see the achievement system evolve to reward gamers who are dedicated to a game for a long period of time, but don't always do every activity in a game. For instance, I play a ton of shooters. Some of them for hundreds of hours. But I don't
always earn all the achievements in a game because I only play certain modes. There should be something that shows how dedicated I am to a game, even if I don't earn all 1,000 achievement points.

I know most already have this but I think they should add a tracker to all achievements. not all games track this so sometimes it's harder to guess when you are near completing it.

idk if that bothers more people

Personally I'd love to see things like gamerpics and Avatar awards return. It was always a nice treat to get new gamerpics from games or items to flex.
