Gemini Rue is probably one of the best game stories I have ever seen. What Joshua Nuernberger did there is amazing. The "twist" that occurs there in the final third is something else. And it's built using AGS.
Yes they still do, and fun fact, SummVM has integrated support for AGS a few releases back, so one of my favourite titles from Wadjet Eye Games, Unavowed, works great on a ton of different OSes/platforms.
