Oh wow, I never realised you could get Gengar in the Old Chateau! You really do learn something new every day. In any event, I thought it had a nice atmosphere for a creepy old mansion, and it was definitely elevated by being Rotom's location. I can't say that I spent lots of time there, other than for Rotom, but at least all the backstory meant that some effort was put into the location and it wasn't just a rushjob. Which is always good.
