For any number of reasons, tell us what your favorite game universe - video game or not (e.g. D&D) - and why.
I would have to say mine is the Warhammer 40k universe or the Warcraft universe. Warhammer is so massive and epic, with all its planets and races, while Warcraft is also great with its characters and countless storylines.
What's your favorite game universe and why?
Edit: And the Witcher. It's so dark and brutally realistic, ahhh its great.
