That's so interesting. I tried to play it years ago but couldn't figure out the rules. It has something to do with six generals trying to dominate the world?
You play as one of the generals leading one of the 6 armies, but you do not have to conque the world to win, only your objective
Do you usually play with two or more players? I would think more players would be better. 
2 is the minimum, but I like to play against at least 3 players.It makes the game more challenging 
I have read that forming alliances is also a startegic part of the game. Is that how you play?
You are probably reading about another game, because you are wrong. I plays this game win all by myself
Okay. Do you play any other games? There's one called Plunder: A Pirates Life that's supposed to be good.
Risk is the only game for me. It is in my DNA to play and win this game
Do they have such a thing as Risk tournaments? Where you play for cash prizes?
Unfortunelly no. We play for fun in the tournments.
