And that eliminates basically 95% of what actually makes the Realms unique as a setting and not just another high fantasy one.
And if that's the reason why you choose to no longer run games in the Realms... because you cannot start a new game in the "Current Year" (whatever that happens to be) and have all manner of detail from across the globe written out for you already... they'd probably say "Sorry to hear that. But there are plenty of other places/times/settings for you to run games in, including making up your own, so go ahead and do what you do and have fun."
