I do not want to control five zombies and three skeletons and my party and also maybe a dog, is usually what stops me rolling necromancers in RPGs. Zombies: quite slow, famously, but in CRPG The Necromancer’s Tale the undead are your party. Seems no-one wants to travel with a guy whose shoes smell like embalming fluid these days. Fine. I’ll make my own mates. Out of bodies.
