Among all the planewalkers here, do you run/play in a post- or pre- Faction War timeline?
I much prefer the pre-Faction War setting, with its kriegstanz, colourful Factols and faction headquarters. Faction War was a good adventure but it destroyed a large chunk of the setting flavour without replacing it with anything equally interesting.
That, and most of the setting books support the pre-War setting, and since the line is out-of-print, that's pretty much all we've got apart from the great (but small) contribution by the PS3.5E folks.
So what's your pick, GMs?
I agree with you on that, Krypter. Sigil just isn't Sigil without the factions. The politics of the city was and always is (in my humble opinion) the greatest, and most interesting aspect of the city.
