Why are you suprized, it's a very correct way the game develops. Georgia was always a fighting nation with good units, but with poor resources and huge hordes of enemies.
This is going on for centuries now, even today we have the same situation, so play the game, imagine yourself ruler of Georgia (don't mean Saakashvili of course

) unite Georgia, receive good authority and thus low corruption, wait untill northern steppes are unified and then prepare for fierce defence against those northern invaders (don't mean Russians of course

), don't forget to fortify and block mountain passes (don't mean Roki tunnel

), because last time I forgot, countless hordes invaded and needed all my allies to fight back, but as it appears TW alliances only work when your armies are standing togather, but no other support (don't mean USA for sure

).
So play as Georgia and recreate or change the history, medieval or recent

, as you like!
