Is there a possibility to play part 1 or 2 on the ps4?
Maybe PS Now?
Yes, with the PS-Now subscription you can play almost all PS3 games on the PS4. (Force Unleashed 1,2, Lego Star Wars etc.)
But next to the game (on ps now) there's ps3 but not the ps4 logo, normally both should be there if ps4 is also possible. That's why I also assumed that it is only accessible for ps3
The logo does not mean that the game is only available for the console, but shows where the game was first released. * ALL * Games that are on PS Now can be played on PS4. Lg.
