Question regarding OV1 + Raising Hell

[Magneman]

Hi, 2 days ago I bought Overlord Complete pack, and I was wondering which game to start. As far as I know, starting either OV1 or Raising Hell and creating a new game will start with the same intro, tutorial etc.
So, does it matter which game I start? Does Raising Hell just expand the original game, for instance if you complete OV1, an extended storyline will follow?

Thanks in advance.

If You have both installed then no it doesn't matter which one Your start as the expansion will load either way. As far as I know the expansion is really only a set of abysses, or extra levels if You like, and an extended end.
