I don't really have any solid adventures in the game beside trying to activate as many cheats as possible and seeing the mayhem it can cause...
But as far as a solid memory from GTAs past... and the reason why I absolutely fell in love with the series rests with Grand Theft Auto San Andreas. In a time when the only games with good stories were JRPGs, San Andreas gave us a "real" story of life in "the hood," something I had never really had known because of my low-class, white upbringing. This story was fascinating to me nevertheless. Stories of love and loss, trust and betrayal, with some of the best plot twists in gaming history. I actually felt a connection to every character in the game and even though I was just some white kid, I felt as if I could understand it all. I'm sure that sounds silly, but I mean, what can you do.
tl;dr San Andreas was and still is my favorite game in the series. I heard that Grove Street is in Grand Theft Auto V. Give me the chance to see that place again in glorious HD.
Thank you for the opportunity.
