Far Cry had the same loop in 3 and 4. Yes, it’s part of the classic ubi formula. Anyway, seems like Unity isn’t in your list. I recall that having about the same verticality as Syndicate, though no grappling hook and maybe less tall buildings. Mostly 3 floor apartment blocks plus some cathedrals. I played 1 year after release and really didn’t have any bugs, in spite of initial reviews
