It was astoundingly buggy, didn’t work at all on multiple platforms that they released it to, was over hyped (part their fault, part community fault), the game felt “flat” and lifeless due to it missing a lot of the small details and better ‘AI’ of the GTA series.

It just wasn’t the game they promised at all. And the fact that they kept delaying it then saying “we want to make sure it’s ship-shape” gave people the impression that the game would be polished upon release, and it wasn’t even close to polished.

It’s improved leaps and bounds since then, though. When I first bought it I ended up refunding it, but recently I bought it again and it’s so much better.
