"I think that in this game you should be able to interact with cliche leaders in free roam and not just in missions."
^ This. However, I am for a whole new game, different school, town, people, Etc.
Now, the other points....
1....Pistols / Guns ? You Kidding ?
2....Water Gun sounds fun, and would do away with the stupid water balloons.
3....Like this idea, dueling / jousting would be a blast.
The Punks should be the next gang. Some older street toughs with dangerous moves.
Shops ? I want a whole lotta other shops, not just for clothes either.
