[GaaS]
1: Some (not all) to PC (also some to mobile)
2: Most of those ported should probably be Day 1
3: Some kind of bonus perks should be given to PlayStation owners buying the console version if online is required, such as free skins or such.
[non-GaaS]
1: Tentpole AAA exclusives (1P) should be exclusive to the console for at least 4-6 years, if not longer/permanent. PC ports should only be within 1-2 years of new console-exclusive entries or new equivalent scale IP from the studio of that game.
2: Tentpole AAA exclusives (3P) should be exclusive to the console for at least 2 years, if not longer.
3: AA 1P games that can leverage console & mobile should do so, with Day 1 availability between both. Some specific AA games tailored for mobile experience even if based on existing IP (i.e like a Pokemon GO!) can be exclusive to the mobile side if desired. Some AA between mobile & console can also be Day 1 on PC.
4: Remakes of very old, last-gen or even older games, that aren't necessarily billed as AAA experiences, can potentially target Day 1 on console & PC, preferably tho when a new entry exclusive to the console is on the way (say 1-2 years out).
5: Remaster collections of much older legacy titles with QOL improvements can be Day 1 across console, PC and mobile (i.e a Jet Moto Remastered collection or Resistance Remastered Collection, etc.). Tho again, preferably also timed with new console-exclusive entries coming within 1-2 years.
