Actually, without the mongols, the age of discover would probably be greatly postponed.   There would probably be no modern world as we know it.    the modern world is born out of the Mongol conquest every but as it was born out of the Black Death.

Also, the Europeans caused the native population of the Americas which they crave to drop by 90-95% between 1500 and 1600.    That is about 20-25% of the world’s population in 1493.    The mongols were comparatively ineffectual amateurs in depopulating the lands they crave.
