For me also before I made the jump to xbox one I got gta and what kept me gripped on the game was the story mode how well I was done.the fact that u could play with all 3 characters was pretty good and the plot twists.
As for multiplayer I tried it and got really bored of the repetitiveness of it so for me the two good things to come of this game where the story and the fact that it netted me the most money when I traded it in to obtain titanfall and to get me rolling on xbox one
