Some of the most fun I've ever had gaming, on par with DayZ. The sandbox is wonderful, as evidenced here you can create the best of stories with even some of the littlest minutia Rockstar has included thanks to their world building and their awesome physics engine, (Euphoria is king, and always amazes me).
At one point during the night I almost passed out from laughing too hard. Pony had been photographing our bike antics from the landing zone of a jump and wasn't ready for the unmanned SUV missile I sent over the jump instead. It flattened him like a pancake as he was stuck in the camera's viewfinder and exploded all the other cars in the parking lot he was in.
