So, should I go for 100%? I have like 85% complete(with the storyline and 17 strangers missions done, I'm working on the last stranger mission) but I still have to do a [censored]load of stuff, challenges, a bunch of outfits, mini-games, etc.
I was at about 85% and it took me a good 10 hours figuring out everything and doing it. It was very satisfying though when I completed it 100%. If you got the time, do it.
EDIT: and the Bureau Uniform is fun to play with. I went into the Armadillo and started killing all the law. It was fun and I got no bounty. I didn't save though, I never do when I go nuts on towns.
