> The Court stated that “perpetual” can carry different shades of meaning, it can mean “never ending” (i.e. incapable of being brought to an end) or “operating without limit of time” (i.e. the licence was of indefinite duration, but subject to contractual provisions governing termination). The Court held that the latter interpretation was applicable.

You can be legally sold a licence in perpetuity that operates without limit of time, but your access can be revoked as long as the terms that were agreed to allow for it. This means that games ending service and no longer being playable is perfectly legal
