Helloo! I have just got the Gold edition MTW. Going to start a new campaign but first I have a few questions.

1. I have played Rome and MTW2. Will I be dissapointed by the graphics?
2. I have played Rome and MTW2. Will I get kicked out of the park by the AI?
3. If a get this far without being disheartened, what is an easy faction to play as for a begginner?
4. Should I stick to medium difficulty?
