What if ariq boqe defeated kublai??

mmh, it would probably the dream scenario for most Mongol fans. here'S my idea: the Mongols would loose immediate control over china much earlier, like the Il-Khanate in persia, however the empire probably would have remained unified and thus very likely have resulted in more waves of expansion, like under the sucessors of chinggis, maybe resulting in the conquest of egypt and europe. japan and southeast asia would have been attacked unsuccessfully anyways i guess.
