The only one I can currently think of is Gris - and I say that because I can't recall buying a game that made me want to get my money back upon finishing it.
Gris is very highly rated across the board, so clearly there's something I'm missing as to why. I enjoy walking sim games every now and then, but it'd be hard for me to even call this one a game. People point to the story as being beautiful and deep, but it felt like nothing new and, for me, a bit trite. There was nothing engaging about this game to me. The worst part? It's like 3 hours long.
Sorry if whomever reads this really likes Gris. I'm glad you could enjoy it. To me, it's one of the worst recommendations I've ever received.
