I love Planescape. One of the only campaigns I ever got to finish was in the Planescape setting. It is vibrant and weird and dark.
What I want to do is start up and build around a group or characters or fair level (possibly about 125,000xp to start) and go from there. I have lots of ideas running from things I have gleamed out of the published material- including the campaign I already mentioned which I may try with a new group here.
There'll be much of the old 2nd edition material I will allow- such as the Kits from many of the Complete books- and options and house rules I use as well. Characters should be built solidly- having stories to tell about their past explots as well that we will work together to create.
This will all be pre-Factol War but such a stir up might take place during play... such things have yet to be decided. I do not tend to use modules as is because I like to create my own things and pepper in that which works for me.

Anywa... come take a look, berks!
