[X] [SITE] Cairo
[X] [GOOD] Belief
[X] [EVIL] Avarice
Hmm okay, so basically I based my choices around what would make for an interesting start, as well as to what I think can make Kane a good ideological contrast to GDI.
Geographically, taking Cairo puts us in close proximity to the Suez Canal. If we take it, that means GDI ships are going to have to go the long way around the Horn of Africa. If we can snag Gibraltar, that effectively means we can turn the Mediterranean into a Nod lake.
I also want to lean into the whole prophet angle for Kane so I'm going with Belief. It's not really Kane if he isn't the Prophet, and GDI isn't going to have any clear answers for that. This also synergizes with picking Cairo as protecting the middle-eastern holy sites like Jerusalem, Mecca, and Medina means we get a lot of goodwill from the religious around the world, particularly in the yellow zones where we do our recruiting.
Lastly, I'm picking avarice because it seems like a good starting point for why Kane fights the GDI, and why he chooses to go to war. The whole idea of the zones in C&C reeks of privilege and greed. GDI while claiming to represent the entirety of Earth's peoples, does not directly rule over a majority of the Earth's population. I also find it a fair bit telling that most of the blue zones are in the global north while the yellow are in the global south. Really though, I like the other options as well but I don't know, something about picking avarice speaks to me.
