BeatriceElysia: I'm opening this thread so I can suggest currently discounted games to gog members. There are some really nice gems out there:
So, purpose of this thread is to bring to attention some of lovely games I have played on steam or gog, but somehow aren't mentioned more:

Let's start:

Mages of Mystralia - lovely action adventure game with lots of puzzles. It features unique magic crafting runes fun. Not too punishing, not to easy either. Characters, story and gameplay are rewarding as hell, and artstyle is candy for the eyes IMHO. Nice music, also

Nine Parchments - twin stick shooter where you play as large cast of mages. Controls are easy to use on k+m, story and world feel a tad bit empty, but it features ton of unlocks, hats, staves, characters to play as, co-op, monsters to kill, artstyle and music are unbelievable mesmerizing.

Honorable mention:
Ghost of a Tale - worth it so much, but it's already popular, Regalia oMaM, Tangledeep, Banner Saga 1&2
