Same as Nintendo, bring the games people want to play and make it only possible to play them (first) on their system.
Difference between Sony and Nintendo is:
Nintendo banks on familiarity, safety, affordability, milking the same franchises since the start, marketing aimed at families.
Sony banks on graphic fidelity, cinematic experiences, pushing the boundaries, multimedia, marketing aimed at teens and young adults.
The two strategies seem to be rather mutually exclusive. Different target audiences with small overlap. Sinking yourself for hours at a time into a 100+ hour RPG fits better on PS while short burst play fits better on Switch.
Anyway to stay in the console business you have to make people want to buy your console. Primarily by providing exclusive games people want to play.
