My favorite game as a kid was the open world game Grand Theft Auto
I really enjoy that series as well.  Have you liked the later versions including the most recent GTA V?  They are masters at Rockstar to be able to create something so incredible.
Yes that one is the best, San Andreas let you play on mobile too. It was awesome exploring California and different stories.
Their stories are so intricate.  What systems to you have now other than a mobile phone?
I liked playing the series on the xbox as well, it was better play to steal the vehicles there.
