Even with consoles in the past I've always tried to 100% my games, that is to say earn everything you could posibbly earn, unlock every last thing you could unlock, and find every last secret. With the 360 we have Achievments that server as a measure of how much of a game we've completed (some work as a better measure then others).
I know this makes me happy as now I have a defined set of goals to easily determine if I've found everything there is to find, and do everything there is to do.
Here are the games I've 100%ed, I'd be interested in seeing what games you've done and hearing your expereinces getting there.
Games I've completed 100% (in order of completion):Tony Hawk's American Wasteland
Marble Blast Ultra
Amped 3
Call of Duty 2
Condemned: Criminal Origins
Games I'm working on:Bankshot Billiards 2
Feeding Frenzy
Project Gotham Racing 3
Call of Duty 2 and Condemned were both a blast easily some of my favorite games so far this generation. Also the feeling of finding all the secrets and getting the extended ending on my 2nd play through of condemned and making it through COD2 on Veteran were both some of the most for filling gaming experiences I've had in a long time. I'd recommend those games to anyone.
