I would go one step further and say that in complicated maps there's complex kismet that simply doesn't make any sense at all.
In order to get around some limitations of kismet, i've had to do some really wacky stuff that simply wouldn't make any sense to an outside observer like teleporting players away and back to a specific spot in a fraction of a second for what seems like no reason. But in the end it allows "broken" kismet actions to function in the long run.
Not sure what you mean by "mappers", are we being persecuted here? "Us people don't know how to adjust gameplay?" Maybe i'm misreading your post, but keep in mind not everyone has been filed away by large gaming corporations yet.
There's always been this wall obscuring programming from the general population, i was never exposed to programming growing up, and now that i've used kismet and totally fallen in love with it, i wonder, had i been exposed to this stuff at a younger age would i still be pursuing art, or would i have chosen to try my hand at programming?
Anyway, i'm going off on a tangent. This is user mods we're talking about here, they don't always strive to be proffesional and often times serve mainly to amuse the creators, programmers or not.
