Bayonetta 2 - The fact that Platinum could run all of the crazy shit in this game on weaker hardware is a testament itself. Then again, they were working closely with Nintendo.
Doom (2016) - The King has returned. Nothing further. Never has Hell looked so glorious.
Wolfenstein: TNO - A true 90s old-school shooter mixed with some new elements without being condesening or overbearing. Plus, it felt like playing a pulp novel in video game form.
Uncharted 4 - I don't care much for the game story nor have I played it, but visually, I'll give Naughty Dog props for the effort they put in.
Devil May Cry 4 - A game released in 2008 that still looks good now is an achievement. A lot of early 7th gen HD games have aged poorly, looking either too glossy, character models stiff and rigged by today's standards, and the ultimate early sin of making everything BROWN. It's too bad the environments are lazily recycled though.
Mad World - I have yet to see a video game do black n white in a video game so beautifully. Once again, Platinum was able to do this all on the weakest hardware. The cel-shading just adds all of the extra layer. And speaking of cel-shading...
A lot of games from 99 or the early 2000s that used them. Jet Set Radio, Viewtiful Joe, Gungrave, and Killer 7, all still look amazing and have barely aged at all visuals and aesthetics alone.
