I have to say I am very dissappointed in the Dragon and Dungeon magazines. When I was younger, i was too cheap to pony up for a subscription, so I would go to my friends house and read his. They were wonderful, detailed, great maps and interesting to read even if I didn't play the game all that much. Awhile back my friend was moving and didn't want his old magazines and I got to be the lucky beneficiary of most of his collection!
When DDI decided to make the magazines online, I thought great I can't wait to have all this stuff on my laptop available. But ya, most of the adventures seem short, lack a compelling story and the maps are shameless plugs for their tilesets. This saddens me greatly. D&D has a large place in my heart and I hope they do not simply make it a marketing vehicle for game related widgets.
I have not updated my monster builder recently, but I too loved this tool. (The only "tool" that was actually released for DMs). If I update and find it is now a broken tool I will be very disappointed. It was a very easy to use and well thought out application, unlike the character builder in many ways. In fact I would have to assume the folks who designed the monster builder were a completely different team from those who designed the character builder.
