Lo-Fi Games

this goes with my post for different cultures
give them different religions that affect how they live and such
this could create crusades as well as allow you to be like a viking and barge into a church when no one is armed and have your fill of loot
found your own religion and pull the masses to you in a quest for power
follow an exsiting one and help them become the dominant
follow nothing(i do this) and make everyone hate you

Something like this was already sugested, and has a small discussion in another post, but was positly reacted if i am not wong, same by me too, +, and i guess we can say it most likely will be present, even if just one, as there are monks in game.
