Heya, Pompe!

Time for me, too, to give you a warm (belated) welcome to our wonderful forum!
But to get to the topic quickly: I absolutely agree with both you and Uriel (edit: and Michael, who dared to post before I was done writing this!).
Engel is 80% roleplaying (REAL roleplaying well-thought out characters, which makes it so wonderful), 20% scenery/tragedy/heroism and 0% hack and slay.
I, not being a religous person at all, absolutely revel in acting out my engel-characters, making the Michaelite talk big about God's will, cursing at dreamseed as a Gabrielite or making no bones about praying to Uriel to lead the way or let the arrow find its righteous way as a Urielite.
This religiousness or (twisted?) fanatism of all things is what makes Engel great to roleplay.
(WARNING, HINTS AT SPOILERS AHEAD!!)
I have played in a few Pen&Paper fellowships and will not hold forth on what unfortunately went wrong there, but the group did in fact encounter the inevitable and faced the truth. I faced the truth alongside my character at that time and was truly shocked.
Looking back at it, it could have gone better, more cineastically, and it was probably my fault as well (never read any corebooks at that time... big tragedy since my initial gamemaster-made-views on Engel have somewhat changed since reding some things..) that things went straight into this rebel-angel-thing-direction, which I think is a difficult direction and does not pay justice to the game-systems and background when you step on that road with the "wrong" host of players.
I have reflected on Engel a lot since then and come to the conclusion that the game lives on GOOD roleplaying and, yes, good indoctrination. Of course it is fun to have a group uncover bits and pieces of the secret, to lead them in a way that will inevitably cause dispute and argument among the Engel of the group, make them doubt, maybe make them act in a way that does not represent the will of the church - but maybe that of God?
I think slapping the group in the face with the BIG secret about their background too soon is not any good and spoils too much of the gaming fun. Even with a group that consists only of "knowing" players.
I would also think that it is contributing to have a mixed group of players, some who have not yet discovered any secrets and some who have read the books, gasped once in shock and awe and then settled their minds on the idea that indoctrination and piety are major and important aspects of the game. That way it won't go over the top, once the Engel discover any of all the little inconsistencies that the church bases its power on.
However, knowing most of the Engel-secrets (at least the BIG one) had me reflect the game and the gaming-mechanics and, in my very humble opinion, mature to an Engel-player that can handle a well-balanced game and design and play characters that do justice to the system.
...God, that sounds arrogant:

Don't mean it that way.
Just wanted to say that a game of Engel can ripen from "knowing" players who can deal with the problems of the Engel-world way better than a virgin-player..
But the most important thing is... a good player. No matter how much he/she knows. That's my opinion.
So, 'nuff said!
