Thomas Was Alone got me back into gaming after a seven-year break. It's a great game!
I love Cook, Serve, Delicious! and would not call it "casual" in any way. It requires definite skill, and it's well-made.
I've seen a Winter Wolves developer on the forums saying their games were rejected by GOG. I would buy some of them if they were here (they are currently sitting in my Steam Wishlist). I'm thinking of Season of the Wolf
and Spirited Heart Deluxe
. I haven't played them, so I don't know whether they are great games, but I would buy them here and find out. The prices on Steam seem too high for GOG, so maybe that's why they were rejected.
