Chalk up another one for Witcher 3. It's simply one of, if not the best games ever made, never mind this generation. To keep up the level of quality it has in writing, graphics, world design, character design, music, quests, and to keep that level of quality up over an astoundingly generous amount of content was an incredible achievement. And then on top of that to release two enormous DLCs that actually surpassed the main game in quality and to support the game for so long after release with patches and QoL improvements, fixing many of the launch issues, is an achievement that I don't actually think will be topped in my gaming lifetime (gaming since 1988).
Most importantly, the way everything comes together is something special. It is more than the sum of its parts. The game has soul. Its characters and stories and atmosphere stay with you. Once I had completed the entire game, which took me over a year, I felt a sense of loss which I've never felt before after coming to the end of any piece of culture or entertainment.
