I just started Shadowrun Returns last night, and am having a great time with it. The writing is top notch, and wouldn't be out of place in a great sci-fi novel. Visuals are obviously great too. Combat is so-so. I hear people saying Returns is like a prototype for the sequels, but I'm getting a lot of enjoyment out of Returns regardless.
I'll post a review when I finish (in the 52 games 2017 thread)
