Just finished the Dragonfall campaign several days ago and I'm still hooked on the game, hoping to play through some of the Workshop campaigns soon.
Isbjorg, If you haven't played it yet I highly recommend it; both the main game campaign Dead Man's Switch as well as the add-on Dragonfall. While the combat is - IMHO - rather simple, just the plot and character writing alone make this game definitely worth playing if you like cyberpunk settings, RPGs and a good story.
There are some differences between DMS and Dragonfall, though. DMS is very linear and has a cyberpunk noir detective story kind of feeling to it. Dragonfall, on the other hand, offers more content, larger and more open areas and more choices. Both campaigns usually do have multiple ways to achieve certain goals, though.
Oh, and the soundtrack is pretty damn awesome, too. Get the Deluxe Edition if possible.
