When does this take place?
Before or after GTA IV?
The amusment park is open in this, but it was closed in GTA IV. So I'd guess before.
Plus I have had run-ins with "The Lost And The Damned" biker gang. The same gang from the GTA IV DLC on the 360.
I've not run into Niko and I don't think he is in this game...so maybe he's not in Liberty yet.
Which would lead me into thinking it's set before GTA IV.
I don't recall a year being mentioned, but I could be wrong.
The greatest trick the Devil ever pulled was convincing the world he is God.
