For years I played Werewolf the Apocalypse, but we never bothered to track Renown, because it was complex and a bit confusing. There's three and a half pages of example rewards and penalties, but they're far from exhaustive.
And of course, this hampered play because without gaining renown you can't gain rank, and thus higher level gifts.
What is a typical amount of Renown to award at the end of a session?
I know this will vary heavily with what went on in the actual game session, but even a ballpark estimate is good enough for me.
