I have been making games for a while now (using Java, C# and Game Maker) and I decided to start making Flash games. But there is one thing that I don't know: which script should I use? AS2 or AS3? What is the main difference between them? I play a lot of games here on Armor Games, which one are they made on (AS3 or AS2), for example Gemcraft?
Also could you point me to a site where I can see some examples for AS (sources etc)
