relatively easy, yeah. builder 2.0, you are right, but for a person who never modded a game before or programmed something, it's quite hard.
It might take a while until you really understand the scripting language, and modelling is complicated at first, too. but if you have practised a while (maybe making some maps) or you have already used other programming languages etc. it's probably very easy to learn some s2scripting.
So Reappy, best try to learn some scripting and go for a map

then try changing a few smaller things in the .inf's and adding some new features to units or copy a unit and make it e.g. a trader
