I guess I'm kinda excited about Cathay, but now that CA shows it is willing to work on minor human factions, I can't get my head around why they didn't make Araby playable. Araby has more lore than Cathay anyways and in my opinion much more interesting.
Now I know Araby wouldn't make sense to be in the third game, but not adding them in the second game is really a huge loss.. I am of course thankful for CA's hardwork, it's all great, but I can't help but be upset about Araby not being playable.
