This is an advice to all of you who think that Bully is way to short.
1) Next time you play it, dont rush from mission to mission. Take your time. Relax after completing a mission.
2) Don't sit infront of your TV 24 hours a day playing Bully. It is bad for your health and you wont notice the cool and fun details in the game because your to tired to see them
3) Between missions, explore the suroundings! Go to the town, look for funny things to do! Help the pupils with things, gocart, go to the carnival with your girl or just pastime in the commonroom
4) Buy new clothes and see how people react.
All of these things will make Bully a longer and more fun game. After all, that is what games are for, make you have fun.
