Last time I checked I don't think you could change the AF settings in a console game.
Only crashes I had during my first play through was entering an interior building, twice when starting up a conversation, and once with alt-tabbing.
Few things I didn't care for (besides low res textures), is you can't immediately level up, you have to wait for a lull in the action/after conversations before you could.
AI "Henchmen" have some wonky-ness to them like picking up EVERYTHING from killed NPC's, not remembering tactics (like stay close, or only use ranged weapons, or switching to inferior weapons like a pistol instead of a rifle, using a 10mm pistol when I gave them a nice shiny perfect Plasma Rifle), if you climb up or hop down a rock they go the long way around because they can't jump or fall, etc.
Guards and NPC's have ESP, and know that your looking at a locked door, or container, and commenting that they know you are eyeing it, even though they are 20 feet away with their back to you.
And no way to continue playing the game. Once ya hit the end, your at the end.
I will say that I did enjoy some of the skills (like Intelligence and Speech) being useful in several different situations.
Overall not a bad game, but still holding Fable 2 as my GoTY choice.
Size Does Matter - Just Ask SackBoy... brilliant.
And finally as for the DVD Vs. Hard Drive, it's obvious the hard drive is better, but what I wanna see is if it helps with texture pop-in, in games like Gears of War and Mass Effect.
