Side-programs for Graal

[Tyhm]

That's because the core tenet of Artificial Intelligence is that everything can be expressed or at least aproximated algorythmically. It runs counter to the human ego - imagine a scientist telling you he could predict your every action with a complex mathematical formula! - and so once we see how an AI works, we insist it's cheating and that it is not, in fact, AI. The only way to make an AI is to throw everything in a Box of Mystery, add some component that nobody understands. Key example, Short Circuit. Johnny Five was only an AI because he was struck by lightning. Up to that point, he was running a complicated formula. After that point, nobody understood the formula anymore.
Another example, Elisa. You know, that "AI" psychologist. It seems to be an AI until you realize it's just a sentance diagrammer with a few keyword recognition routines. Then it's just another stupid program that cheats to make you think it's smart.

Point being, as long as there are rules for converting Classic script to NPCServ, there is an algorythm for it and, consequently, a way to make an assimilator do it for you.
