Bon sang, j'avais raté cela lors de ma première lecture!
An "end of tribalism" event will be included for Mamelukes and Persians in case they are played by humans. This event changes the government type from a tribal form to a despotic monarchy. The 50% tech cost penalty for tribal governments appeared quite uncompetitive for multiplayer, hence the need to change governments if those countries are played.
Cela change tout si je veux jouer les Mamelouks!
Il est bon ce mod je vous dis
