Yeah because in some ways it’s unrealistic. But we need a decision on what the “expected lifetime” of a video game is , I suppose. Much like how for rental flats there exists standards how long a kitchen, a bathroom, etc, last on average until they need refurbishment.
So if it comes down to say 10 years, then you cannot shut down your online services before those 10 years are up. As video games can be expected to last that long. Although I wonder whether this means they could shut it down after 5y if they refund everyone 50% of their sales price.
