I loved the carriage stuff in Syndicate, too. :-/
And yeah, the grapple gun was a handy thing to have. But I love the fact that in Odyssey you can basically scale anything. There are virtually no obstacles in the game that cannot be climbed over. When I first arrived in Athens, I was like, “Let’s get to the top of the Acropolis, and screw the Propylaia!” – and then just flung myself unto the rock face and climbed straight up.
I do not recommend doing that in real life.
