Vice city has my favourite GTA storyline, not just because it was my first GTA game, but because the story was epic. The characters (I liked them, some of them were funny, and I still remember most of them), the setting, the music, the story ...
The ending was sweet.
GTA V had an "ok" story, but it could have been better if half of the story wasn't working for the FIB. GTA V just doesn't have that magic Vice city had. Franklin becomes dull after moving to vinewood hills, Trevor is too crazy, but Michael was, overall, a good protagonist, but he has his flaws as well. Unlike these three, Tommy started from the bottom, just released from prison, and he climbed the ladder all the way to the top, the Vice city crime boss. While VC had a good ending, V had 2 sh*t endings
, and the other
was not as good as Vice city's ending.
GTA V could have been better if there was less FIB missions, and if there were more heists.
