Play got my copy to me today. Played for an hour or two, am enjoying it. Liking the iron sights, vistas (though not enough grey atm!) and I'm glad I have spoiled pretty much nothing.
New perks etc is making me excited just a tad, just getting straight back to picking up the odd stimpak and unlocking safes... S'all awesome!
As for the PS3 patch: I started playing it at around 4:30 for an hour, had a 15 minute break, rebooted, then the patch was up. Thought it was a bit quick! Ah well, I haven't had any bugs. Yet. I thought I did have one when a woman asked me to shoot some bottles on a fence, because I couldn't see any, turns out I wasted a couple of ferlongs reloading a save file when it turns out they were behind me near a building. Muppetz.
Early signs of hardcore indicate it is manageable, however I won't be happy til I have a permanent bed. And have good supplies of food etc. Water is in plenty supply at one location so that's fine for now, and heaven forbid - no rads!.
