Andy_Panthro: Well I have to say, if anyones thinking of getting Batman, I'd recommend it. Not sure if it's quite as good as the reviews say, but I haven't got very far yet.
One of my first forays into stereoscopic 3D, and it works really well. (mind you Batman does look very good as normal, so I'm sure that does help!)
I did get a bit of a headache after an hour of playing though, which is a bit of a shame. Not sure if I'll get used to it. I was wondering about those new 3D films though, if I get a headache after 1hr, then a normal film (at least 90mins), wouldn't be very good. Thankfully you can switch the 3D vision on and off very easily.
Shame you get headaches. I recommend Tomb Raider: Anniversary and Need for Speed: Shift if you want some more cool 3D experiences, but if it hurts your head too much you shouldn't bother.
