Don't know if anybody interested but GOG has updated versions of several older games on sale. For example:
Full Throttle Remastered $9.99 (33% off), Grim Fandango Remastered $3.79 (75% off), I Have No Mouth and I Must Scream $1.19 (80% off).
I've played the original Full Throttle and Grim Fandango but never I Have No Mouth and I Must Scream
Adventure Game: Broken Age, Tesla Effect
Casual: none at this time
Darkside: The Witcher
