Everything pretty much. I can't code or map or anything like that.

You don't need to code for SP mods (yet).

Actually, as far as I know, the main bulk of all SP mods are simply maps driven by ICARUS scripting (which is piss easy, from what I've seen).

Dang it. I meant scripting. Not coding. Although SP coding would be cool.

Is it simple to use an existing map and put NPCs in it? I remember trying to find that to start out with a long time ago and couldn't find any tutorials at the time.
