This is one of the first things I considered when that pic got released (storm looked ****ing epic btw the ocean looks amazing), but I doubt it. I think the lightning will always be just a visual effect that happens somewhere in the distance. tbh, I'm not even sure getting hit by lightning in the game would actually be any fun.
it was actually the first thing i thought of when gta 5 was announced
i vote yes for lightning strikes the main characters
So, lightning. If it were to happen on foot, out in the wilderness somewhere more than, say, twice I can see it being annoying. But if you fly a Dodo through a thunderstorm.... Now that could be awesome.
