I always felt that super script-heavy games were basically there for the flashiness.
When it comes to the number of things in a game (especially an indie game where almost none of the engine is original) I like to keep the scripts down to a bare minimum and only get scripts for things that would be too tedious to event.
Even then, as I am not a fan of too many minigames, there isn't much that I could justify putting in. As far as scripts go, I find that, while battle systems bloat the script count, they are necessary sometimes.
Of course, I'm thinking of trying to make a game with no combat whatsoever so that I can just have the bare bones of the engine that enterbrain gives you with little more than MA's ATS (which is 100% essential).
It would make for an interesting project, but that isn't the point of this discussion.
Zylos, with you being one of the greatest makers here, I think that you provide a good insight as to how to determine what is essential, what is nice, and what is unnecessary. I like to keep things at an essential level as of late, but some things that catch my eye, or some things that would show off my eagerness to include original artwork are good for providing an original atmosphere.
Of course, this can definitely tie in with my discussion of original content...
