Hindsight is 20/20 but you don't have the luxury of that in the moment. By the time Game Pass is a proven model of success it will be too late to mount a response. Sony could adopt the Disney+ model and say pay $9.99 a month for the service and get the back catalog while all new games are $30 or after a year included at no extra charge.Gamepass still isn’t a proven model of success. Microsoft has yet to put their own AAA games on the service which is what you’re asking sony and nintendo to do
Would that cause some short term pain, maybe? But it would give their fans something to fall back on.
