MGS V sold well, probably didn't outsell The Witcher 3 and Batman cause it didn't have as much hype and there were some doubts about its quality due to the Kojima Konami fight. Also it has microtransactions. It will probably have good legs though.
Mad Max released at the wrong time. Gears Of War UE and Until Dawn would have sold better in a quieter time like June or July. Same with Tearaway, which will likely not sell well.
