(I don’t think there was any drama in this because the sales target was understood going in, and I've spoken to him since re: other projects. Also, I don't know how much Versus Evil's and Fig's marketing pushes really helped, so he may have been hobbled from the outset.)
I'm a little biased on VE and Fig b/c I don't think VE did much do get Banner Saga 2's awareness up, for example, and even companies working with Fig have criticized how much the platform helps with awareness (esp. vs. Kickstarter awareness).
How much promotion did Kickstarter do? FIG was really quiet to be honest. Versus Evil is very small publisher that apparently has very limited resources to use. Both Banner Saga 2 (maybe even 3) and Deadfire suffered from being published by VE. Their marketing pushes have been more after the actual release than before it.
With Paradox you get your game into retail stores across Europe. Physical copies are still viable in some European countries, and when you miss out on that you are missing out on customers.
When your game is available online only, it's way easier to have people just waiting for the price to drop. Instead of people picking up the physical copy because they saw it at a store and will actually get to add a box to their shelf of games.
With Paradox you also have Paradox's own fans that are enthusiastic about their games. Does Versus Evil have any fans? I seriously fucking doubt they do.
I don't know whether FIG was the thing that made Paradox back out on publishing Deadfire or the strained relationship when it comes to publishing Pillars and Tyranny, or was it just greed from Feargus and the other owners, but choosing Versus Evil as the publisher was a mistake. They brought very little into the table, while taking a cut for themselves.
