And obviously, if there are more villains in the thread - being controlled by different players, ideally - we can obviously fit more heroes in. But I think a hard limit of "no more than 6 or 7 heroes" would be a good idea. So the max size would be 9 or 10; that is, 2 or 3 villains and 6 or 7 heroes to offset them.<br/><br/>But as a general rule of thumb? 4 heroes and 1 or 2 villains as a max is a good starting number, and we can tweak it as we go along if necessary.
