I expected RK to attack me but not after 10 turns . However, the key can be to kill Dunland very fast. I don't know how it can be possible, cause the rebellions always take at least one city back to Dunland. After this, its impossible to kill them before RK betrays me.
Hmm... maybe I need to restart the campaign on the 'home tea' difficulty level .
Btw the expansion is great \o/, I found no bug yet , no CTD, no crashes. EAX is working very good, the sounds and music are awesome!
And RK...will pay a very high price for being a traitor
