I remember playing Rebuild as a free web game. It was fun, casual and interesting. This version doesn't seem to have enough polish and extra features to warrant buying at 10+ $ in comparison to the free web games Rebuild and Rebuild 2. However it does seem to do better in that regard than Sickness Inc. which is a spin off from a free web based game as well. (Review based on past experience with the browser versions, did not buy the game)
Shadowrun return is an enjoyable rpg set in the Shadowrun universe. It is however not perfect. The included campaign is rather short and linear. However there is a good number of fan made campaigns available. This is important, as the game was made with user created campaigns in mind. I still feel they could have included at least 1 more though. I finished the included campaign in around 8-10 hours I think, and it could have been faster since it was very linear. Still enjoyable though. Anyways, Shadowrun Dragonfall is supposed to be an improvement (haven't tried it yet), and a lot of newer user campaigns need Dragonfall to run. So you get a better value for your money by buying Shadowrun Dragonfall instead.
