I bought a Ps4 game at Amazon wanted to return it because I don't like it but there were stickers inside of the product but they were used but I can still return it or not?
No, you can't generally return it. Open games are excluded from the return.
I don't think the Amazon does not accept it anymore. You can try it. In the worst case, you will just get it again. But I also don't know how it is with games. I sent back two articles after I opened them and accepted them.
No you can't. The right of return expires when the packaging is removed.
There's no right of withdrawal for:
Sound or video recordings or computer software in a sealed package if the seal was removed after delivery
How not like? You opened it and played it? XD
