Of course NWN was (in theory) balanced with the point buy system in mind, with high ability scores actually being rare. Whether that is the case or not (especially when using Epic rules) is a matter of debate.

But BG is balanced on the assumption that an 18 or two isn't all that hard to get with a lot of patience and little min-maxing (or was that the other way around?). Average scores are absolutely meaningless (you don't get bonuses in most cases until 15).
That's less of a BG thing and more of an AD&D thing.
The BG2 NPCs are specially powerful compared to your average AD&D party.
