Great demo, very polished, almost a full game in itself.
Plenty of replayibility, different characters, different parties, pets, items, etc.
Very Impressed, considering I wasn't a huge fan of DS1!
If you have broadband, it's worth starting a download and letting it run in the background a while.
I'm glad GPG released it so big, I wanted the full PCGamer demo but didn't want to buy the September DVD mag to get it. Instead of waiting weeks for the demo, I just had to wait a couple hours.
