I remember playing the original GTA, as well as GTA London. In my opinion San Andreas was the best one of the series, gameplay wise. A lot more freedom on what you could do. GTA IV was a huge disappointment in my eyes, I appreciated the story and graphics for the time but still felt like they took a step backwards in terms of what made the series special to begin with. GTA V was enjoyable, the first time round at least, and I especially enjoy the first person mode, but ultimately I think it fell short of what it could be. I'm definitely going to buy GTA 6 when that arrives, and I hope they do better.
