Played three hours.
1) Graphics are pretty damn good. And I didn't expect to say that, because the 360 is an ancient piece of hardware, but they are pretty good, tons of detail inside buildings
2) First major bug I had is on the yacht theft mission, when Franklin is on top of the car if I crash the car he flies off. He then gets back into the car, not on it, and then despite catching up to the yacht he never gets out and the mission is impossible to finish. I noted surprisingly that while this was happening and I couldn't finish the mission that 100% of other vehicles on the road disappeared; it was entirely empty except for mine
3) How often does the cropduster land at the airport east of the lake? I saw it land once, got in it, but the cops got to me before I could fly off. I then went back and waited 20 min but it just flew around and never landed
