Your avatar, basically.
You've done like, two sh*tty GTA fanfics, an AC fanfic and a Fallout fanfic, not a whole lot to go on. You need to put more focus on characters or create your own story that isn't a fanfic. Create a world of interesting characters and locations, I'd read that! If you're going to do a fanfic, do something different and not just a complete copy of GTASA, like, the main character's a cop or family man or something new and different that isn't in the games. I hear your next one is going to be a fanfic on Sleeping Dogs, instead, why not be inpspired by that game and make your own triad story and characters, it would be much better.
Believe me, I'm a staff at
BUYGIV, I'm an expert on GTA fanfics. Take my word for it.
