For me there's a subtle difference between what I think the best game ever made is and what my favourite game is. I think The Witcher 3 is the best game ever made by almost every possible measure, but Baldur's Gate II is still my favourite game of all time and probably always will be. If I had to choose my five desert island discs, it would be the four from Shadows of Amn plus the Throne of Bhaal disc (yes, there was a 2 disc version, but I'm making a point
). I would choose it over W3, even though I recognise that W3 is the better game in most respects.
