The level that grew the most on me over time is Marrakesh. In H16 i didnt like it at all. It felt too disjointed to me. Like two fortresses and a lot of nothing between them.
When H2 arrived and i had to do all the mastery and challenges again, i was already over the first impression bit and started to like it for what it is. That being the level design from a visual standpoint and throwing you back a little too earlier entries like murder at the bazaar.
Traversing the rooftops is a lot of fun in contracts. And the very good bonus mission used the map more to its strengths. Even more the night setting even more works very nicely here.
Anyway, i would love IO to use the map again in some way or another. Even for another escalation.
