I'd just like to jump in here and say how truly wonderful PC Gen is.
I use it at home and at work and it has gotten much faster, much more stable, and remains very comprehensive.
I still have to reference my books to find out what feats do, class abilities do, spells do, etc, but if I've already got it in my head, I can whip up a PC or an army of NPC's in little under 10 minutes complete with a spell list from Book of Eldritch Magic I & II, Relics & Rituals, Tome & Blood, and Magic of Faerun along with magical items from all of the above, Masters of the Wild, and the Psionics Handbook with If Thoughts Could Kill complete with prices and the adjustments made to the character sheet.
Heck, I'd use the app just for the ability to put characters into html format for e-mailing or web posting. How many good examples of filled out character sheets have you seen on the web lately?
I just finished putting together an ogre/goblin/hogoblin fighting squad with the phalanx fighting feat from Lords of Darkness, Team Fighting from the Fantasy Community Council's latest revision Netbook of Feats, and Spear and Shield fighting from the same. Then I exported it to a party format html and on one page got all the combat info I need for them all. Now all I have to do is throw the chits on the table and go.
The fact that I could throw deepwood sniper levels on the hobgoblin archers inside the shield wall is just gravy.
I've fleshed out an entire order of Knights Hospitaler including knights apostate, chaplain, errant, and a few brigadiers and lance corporals. Ask my DM how handy that came in when 17 of them came over a rise as mounted cavalry to aid us in taking a fortified encampment. Instead of making up numbers they were all right there with sources and everything.
Extremely useful software, and if my 45 lb backpack says anything about it, it says that it isn't costing WotC or anyone else a dime. It's just helping me use my books more efficiently.
Go PC GEN!
