Plus an earlier spread of Christianity to the Far East, which would have interesting consequences. And more connection between Europe and India. Wasn't India just as divided as Europe around this time, with many small and large nations jockeying for control? It would be fascinating to see how the Indian and European lords/explorers and whatnot might try to play off of one another as they scheme for power.The main advantage of a crusader Suez would be the main advantage of our Suez, European trade with India and China and the general "Far East". The Silk Road as a round trip on average took 2 years, that would be exponentially faster by ships, even Crusader Era ships with a more reliable cargo capacity. Not necessarily greater, some of those Silk Road Caravans were massive, but more consistent.
