Bully is an excellent game that is essentially a GTA for a younger age (teens)
The game stays in the Rockstar tradition of beat anybody up that you want. And even though you're only 15, when out in the city, police WILL arrest you.
The game puts you in the shoes of Jimmy, the bad boy with a soft spot. Even though it may seem like you're a bully, it does give you a reason for doing so. Your job in this game is to take down social cliques within Bullworth Academy, eventually teaching them a lesson about bullying themselves.
The clique takedown technique follows the same formula, but does a great job of not getting repetitive. In most cases, a few missions involve a girl. This may be going out with one, or taking pictures of her cheating as evidence to bring to the master of that clique.
Now, usually you can get away from police or those pesky prefects that are always on you butt. In school, you can hide in trash-cans or lockers, in the city, you must find a trash can to hide in.
Now for the class system. Everyday you have a morning and afternoon class. If you do not attend too many times in a row, you get sent to detention. The classes are not all that useless though. WIth each class you pass, you earn an upgrade. For example: In chemistry class, you gain the ability to make itching power, firecrackers, etc. When you pass all five sections in the class, you no longer have to attend, earning yourself more time to do missions. Your classes do not take up that long, however. One short minigame ranging from less than a minute to about 3 and time skips ahead to your next class. After your second class, you have about 7 and a hlaf in-game hours to do missions before the prefects come after you for breaking curfew. If you stay out too long after curfew (2 a.m), Jimmy automatically passes out and you wake up at school.
The missions themselves are almost always fun. From getting girls' panties from you gym teacher to killing a giant venus fly trap for the biology teacher, the game is fresh and fun.
Bully is an excellent game and if you don't pick this one up, I feel sorry for you.
