First let me say that RoM + AND makes an awesome and addictive gaming experience.
After many weeks of enjoying these add ons, here's an advice :

- Avoid using the mega version, the full or lite are much more stable and less demanding for even a top end computer
Also you wont get the black screen land tiles

and a couple of questions:

- Playing Mastery Victory: Eradicating all comp civs should stop the game.
Having hundreds or thousands of turn to wait to finish the game is unplayable.
Is this an intended feature ?
- Upgrading some units actually sometimes gives money instead of costing any.
( ex upgrading to musketman). Maybe a small bug or i missed a rule.

Apart from these minor probs, congrats for such a great work :)
