The $4.0m Stretch Goal - Enhancing the Whole Game

A stretch goal can be defined as, "that cannot be achieved by incremental or small improvements but require extending oneself to the limit to be actualized". As such, I don't think that "improving the entire game" can be considered a stretch goal. They're not pushing themselves to a limit in some manner; they're just executing what they are going to be doing anyway. I think this is why there's a question here: they're not really pushing to a limit if they can't measure what they're striving to achieve.

It can be, I'll give you that. However, I will just say that I really don't think that by deciding "with another $100,000, we'll push ourselves to the limit by implementing, say, a stronghold! Which should cost a lot more than $100,000, but we're going to do it at that funding amount anyway!"

I could be wrong, but I just always read the "stretch" in "stretch goal" to mean "we're reaching towards this amount of funding, and here's why you'd give us any more money than we've already reached." Not so much, "we're really pushing our existing resources further than we'd've done if you just stopped pledging at this point."
