I generally play most of my games with 3 people. ME, my best friend and my brother, it does sometimes end up with a bit of unfairness with people ganging up (mainly on my brother
) but generally i find it is more fun than a game with 2 people, as there are many more tactical options for you, and you have to build an army that can contend eith 2 armies rather than just 1, the game is also generally more fun, especially in special scenarios such as Take and Hold.
Also it saves time haivng to play against 1 person and then the other, although you can always do it that way if you want, and also there is the advantage of having an Independent Ajudicator (the person not involved at that point) to solve disputes overs dice rules, rules or whatever crops up, this makes the game fairer, even if it does take slighty longer.
It also feels better when you win because you have beaten 2 armies with 1 army, double your points!
