I have been toying around with the idea of great classics being remade on the Xbox 360, and one of the things I would like about this idea is the achievements (I happen to be a stickler for the achievements). basicly you take a classic game (or almost any game not for 360 for that matter) and add your own lists of achievements for that game.
For those who do not know, the following 3 articles are used when it comes to achievements:
Name - the name of said achievement
Description - The discription of said achievement (sometimes it just gives you a randomly stupid statement instead, like "good job") some achievement discriptions also change after you recieve them (here we are only using the discriptions for telling how to get, and maybe an optional message for said achivement)
Gamerscore - the amount of Gamerscore points you recieve for unlocking this achievement (I've seen it range anywhere from 5 - 30 points in incraments of 5, and have seen it go as low as 0)

There are also icons to go with the achievements, but i don't think we need to go that far

For an example, i will do a list of achievements off the top of my head
