If a Darksiders 3 does ever come to pass, I'd be down with following either of those two, as long as the plot is not like Darksiders 2. 90% of the story feels like filler where Death goes around collecting stuff to move to the next world, after which he gets to another world where has to collect 3 of something to visit a king, after which the king tells him to find 3 dudes for him...
It was fun visiting all the different worlds, but plot-wise Darksiders 2 didn't have much going on, at least in my opinion. I doubt Darksiders 3 will ever be a thing because THQ has been bankrupt for a long time now, but if it does happen I'd like to see improvements on the plot.
