I have been playing at noble on vanilla and now usually win with scores ranging from 8192 to 22700 depending on who my leader is. I also had one score of 64326 when I used the horse archer rush playing as Ghengis.

I have recently acquired Warlords and BTS and want to know whether I should move up a level or switch to either Warlords or BTS.

What do you think?

Switch to BtS. It includes everything from Warlords except the scenarios. Play a game or 2 to become used to the changes made especially better AI, espionage and Corporations then consider moving up a level.

I agree fo to Bts mabye play a game or two with that on Noble and then move up.

Pat.

It sounds like you probably should've moved up a level long ago. I think you'd do fine on Prince - even if you're not used to BTS. Since the AI is a bit slower paced in BTS, I don't think Noble will give you much of a challenge.

Switch to BtS, play one game on Noble and then take the jump to Prince.
Be warned, Prince is somewhat different then Noble :)

Put in the Warlords CD/DVD and play the 'Rise of Rome' scenario ~ imho its their best one ...

Thanks to all for the advice. It looks as if bts is the way forward.
