I did regard the presence of V5 in the Top 5, for three consecutive quarters, as a big explanation for Modiphius choosing to publish the license, despite White Wolf folding after a difficult year.
For White Wolf, who may have been hoping to recapture the whole WoD market they controlled in 2004, V5 didn’t quite get there. For Modiphius, however, V5 is evidently their biggest hit ever. It was a similar tale with Games Workshop abandoning Dark Heresy and the 40KRP line immediately on release. It wasn’t considered profitable enough for GW, but for Fantasy Flight Games who took over the license, it was a big hit. It just goes to show how different companies have different measures/scales on what is successful or not.
Regarding other titles, it looks like the D&D/Pathfinder dominance (in that order) looks here to stay. Star Wars may decline, I suspect, as Disney takes a rest from making new movies. The biggest surprise for me is that Savage Worlds has never been ranked. There are no 'Powered by the Apocalypse’ games either, although Fate made a breakthrough for a while.
