I got the game around 1 month already and play it like hell. I use to play 1, 2, 3 and 6 players games. 6 players is to much in my opinion since it take to much time and also lost some atmosphere if players don't know the game and theme. I think the best is 3 or 4 players.
Anyway since i play mostly solo i play mostly with 2 investigators. Then i decide to play with one investigator and meet really serious challenge ( i like challenge).
In the end of the day i manage to beat every AO with only one investigator! Leo for Shubby, Silas for Cktulhu, Noman or Diana for Yog and Azzatoth.
Just a curious some one manage to do it also?
