A Necromancer is a talented individual whose talents are rejected by society. They know how to set goals for themselves and have enough perseverance to achieve them.
In my experience, Necromancers usually have only two motivations:
1) A maniacal thirst for power
2) A maniacal thirst for knowledge
With the exception of all sorts of "humanized" Necromancers, but as a rule, we are presented with the first two options.
You're right, but you're saying it as if it's a bad thing.
and you can also use the undead for menial tasks, so they can clean and do other things, so you don't have to waste time on it yourself.

I heard that all the "trilogy" compilations are buggy to some extent. Why not play them separately? Isn't the graphics not that important in the first part? And is it really that hard to transfer the character file from one folder to another?
