A friend of mine is a programmer in college, and he says the logic behind it is easy. You just have to learn how to code in conditions, situations and stuff. I mean, he's really good, he's been giving classes to other students on how to program games for a few months now, at his professor's request.
I don't know how MK works, but from what I've learned about logic and logic languages, it's pretty easy to write sentences like the ones I wrote.
Saying "it would be already gone by now if they wanted to" is not the explanation I'm looking for. To me, it sounds like "if they wanted this game balanced, it would have been since day one". There are many bigger issues to solve before a game is released, the balance being one, and they couldn't get it right. I think you are speculating too hard, Fraud.
