What's Your Favorite Game of All Time and Why?

Legend of Heroes Trails in the sky : im a big fan of J-RPG but i did not intend to play this one since it was in English and ( i didn't speak english very well back in the time, well actually even now ... ) but it was like the biggest discovery for me, this game have A LOT, like seriously A LOT OF DIALOGUES, and yet i don't know it is more like a game, its like you become closer to every character and this is a all series, you have 3 Legend of Heroes trails in the sky, after that you have another 3 series that will follow another military town, and again 3 more in another series, and what's amazing is that they are all linked ! So yes this game for sure blew my mind
