Gamespot has compiled a pretty decent article on how to earn what can be considered the easiest 6,000 Gamerscore points for the Xbox 360.
Madden NFL 06 has plenty of extremely easy points up for grabs in its 11 different achievements, but if you really want to get the full thousand, you’ll actually have to (gasp!) play some football. Let’s start with the achievements that don’t actually require any real work (thanks to the magic of simulated seasons and franchises).
At the end of the article they go over a quick, smile, shrug or thumbs down rating on how easy it is to gain gamerscore points in the current Xbox 360 titles, very nice touch.
