So, how do you play this game?

[Fate]

Ok, so I just won my first game (as the Senator). My first games were all as warriors. My observations so far:

1) The weapon master makes your armies MUCH more powerful. The baron starts with one, and I got one as a Senator. Very good.

2) Wizards are worth it. That is what (I think) allowed me to win as Senator: I saved my cash and got one or two of those random wizards and arch bishops

And my rating of the warriors:

1) - Baron. Higher taxes and free weapon master.

2) Senator. Cohorts are that good.

3) Barbarian - mostly because of the occasional minotaurs and bear warriors.

4) Maharaja. Elephants are too expensive to just be a meat shield (I think).

I would like other's opinions on these. I would also like to know what the Senator's Slave Girls are good for (the manual doesn't say).
