If you're doing the Britannia campaign I may be interested in playing as Llywelyn ap Gruffudd, not played much Total War but am generally familiar with other RTS games.

Excellent, so you would master the Welsh Rebellion then, Wales always my favorite faction to play as it was the most challenging and interesting.
I'll reserve that for you if you would like.
