I bought GTA 5 via ps4 in the PS Store but if I want to go to the PS Store via my ps3 and want to download GTA 5 it costs money. Who can help me?
You bought GTA V in the PS4 store and not in the PS3
PS4 and PS3 stores are also separate stores, also had to buy new GTA V for the PS4
PS3 games are PS4 compatible, and not the other way around, at times Rockstar no longer transferring progress from "Old Gen" to "New Gen"
The PS4 is not backwards compatible.
Each game stands for which platform it is: PS3, PS4, PSN, PS Vita.
So if you buy a PS4 version, you can't just play it on PS3 unless it's a game where you buy both versions at once (but that's rarely the case mostly with indie titles).
The ps4 servers for gta 5 are much different than on ps3
It also stands, even if a little complicated
