Personally, I think some of the achievements will include
1 for each girlfriend 1 for each chapter beaten 1 for completing the rubber-band ball 1 for beating the game 1 for collecting all the G&G (Grottos & Gremlins) cards 1 for all the clothes 1 for each passed class ect.
So this is pretty standard achievement stuff. What do you guys think? --- "Some how, when I beat Bioshock on normal, and went to hard, the Big Daddies seemed easier! I must be crazy!"
1 for like 20 times hiding in locker 1 for 20 times stuffing people into lockers/trash cans 1 for beating each of the money jobs (paperboy, boxing, etc.) 1 for completing the yearbook and for an easy one 1 for playing 20 hours --- Don't worry, ..., There's no such thing as 2.
