Necromancy doesn't work exactly as it did in 2.1. Although, the principle is the same. At the start, you get more Town Experience (TE), heroes give more TE, but there are fewer buildings in the castle. Today, I installed and launched the first mission of the Necropolis campaign. At the start, you have 252 units of TE.

I would have installed 1.5 yesterday if I had known that the game wouldn't require the disc after the patch. Today, I downloaded NoCD, and after installing 1.5, I found out that it's not needed. Now I'm going home and will install 1.5 there. I hope my daughter doesn't kill me for making her replay the mission (she's playing through the first campaign).

I downloaded the patch yesterday from the Nival server.
