For scripting, I don't know, I don't handle that stuff. In general, I'd say you would probably have an easier time using RPG Maker 2k3, if only for the fact that, since it's older, there are a ton of tutorials for it and plenty of experienced people who know what their doing and are willing to help. A good place for 2k3 tutorials is Gaming World, which also has forums devoted to helping people with these and other game making programs.
