Several interesting things to point out about Askia... Mud Pyramid Mosque Costs less to build than Temples. Costs no maintenance Does not require a Monument in the city! Provides 2 more than a Temple. This is the same size culture bonus per city as Napoleon's trait. It's available a little later than his trait, but lasts the whole game. Provides extra culture if near any clothing-based resources for the imams to wear (cotton, fur, silk, dye). Askia's trait tripling gold from barbarian camps is more valuable now that the number of barb camps is doubled in TBC. A Songhai army needs few or zero siege units since Mandekalu Cavalry start with the Siege promotion. This makes him a highly mobile city-capturing force like Mongolia. I find Mandekalu more valuable than both of Napoleon's UUs combined... available earlier than Musketeers and useful longer, and Foreign Legion appear too late in the game to be significant. It's also easier to beeline to Mandekalu in TBC than vanilla, because Chivalry does not require Currency in TBC. Some food for thought.
