[disc/question] How do you organize your code?

[Gogafem]

I code all my games in AS2 without any problem, and without any need for AS3.

It's really just personal preference. I like Actionscript 3.0 better though. Not just because of the syntax, but also because of all the game libraries available for it(Like Flixel, Citrus, Starling, Box2D) and 3D(Away3D, Flare3D). Also it's faster.
