I'm not 100% sure but I don't think PS3 games are included in the promo. The ad only states PS4, XBOX ONE and Switch.
Also confirm the +5 bonus working. Thanks for checking 2.50 base not working.
I tried gta v for ps3, no bonus.
Edit: Nevermind. I see what you mean now. You were just testing it out. I'm sure a lot of people were wondering if it would work with previous gen games.
