No, it hasn't been made by the fan community, but rather, it's been made specifically for the fan community. However, that doesn't mean the rest of us can't enjoy it also.
I've said before that Spec Ops: The Line looks like an amalgam of Mass Effect's cover shooter aspects and Modern Warfare's realism and action, and I've shown you the pre-order goodies. If none of that stuff interests you, then maybe the fact that it's set in Dubai does. At least it's got a new setting.
