I'm still playing The Witcher 3 and although it took a fair amount of time for me to fall in love with it, once I did, I fell hard. The quests and NPC's absolutely blow me away. On the PC the world is absolutely gorgeous, jaw-droppingly, stunningly gorgeous. And most importantly for an RPG, the decisions that you make while playing have big time influence on the world and the characters around you.
It's hands down the most impactful RPG that I have ever played, made even moreso by being a fan of the lore and the books that spawned it. I have no problem with any accolade that the Witcher 3 gets.
