I just bought the Remaster, so I don't have the Trophy yet, which I understand hurts my credibility. That said, I did this as a 13 year before trophies existed so my technique is proven.
My strategy is simple; mute the tv. It can get confusing as the lightning and the thunder don't always sync up. And if you react to the sound, you can still get struck. But you aren't dodging thunder so it's really irrelevant. Mute the tv and you can just react to every lightning strike. It makes this so much easier.
