Hi Polianna Martin!
I really love the GTA series of games, I've been playing them since I was a kid.
I prefer GTA 5 more, I love the story, the characters, the graphics and so on.
In order for you to make up your mind I suggest you visit this site https://gamesrift.com/blog/gta-4-vs-gta-5-top-differences/ and read an interesting article that compares these 2 great games.😻
