Games list has been released! I honestly can't tell what the closer will be, but my money probably would be on SMO Darker Side if I were a betting man. But then there's Celeste All Chapters, FF9 Any% race, NieR Automata E Ending, Wind Waker HD 100%, and Twilight Princess All Dungeons that could close instead. (Or SMRPG Any% if they felt like repeating SGDQ from several years ago!)
