Alright, so I'm going to be making a loaded statement here. I've read Cubicle 7's works, primarily the core books for WFRP 4th Edition and Soulbound (and a few other books for WFRP 4E), and I think I can make a few statements about Cubicle 7's quality.
They're good. I like them. I think they're lovely writers who are progressive in their views and that they actively try to be inclusive, which I love. They have lots of art, they credit their artists and writers, something GW doesn't even bother to do these days, and they're inclusive with lots of racially diverse and LGBT characters. They are excellent in their creativity and providing ideas and hooks for authors to latch on to, and they make good books with lots of varying options for GM customisation and they encourage budding GMs to customise their own game and create a healthy TTRPG environment.
But Soulbound is better than WFRP 4E, and here's why.
Cubicle 7 are trying to be something they're not. I can clearly see them struggling to some extent with the WFRP property as they attempt to mimic the old style with their own spin on it, and it's not working out as well as they might think. Their style doesn't mesh super great with WFRP. WFRP is too crunch heavy and dark and gritty, and Cubicle 7 don't know how to manage that line properly. Not that the previous authors in 2E did when making campaigns, because those were edgy as hell and over the top grim. It also doesn't help that Cubicle 7 are trying to bring back 1st Edition in 4th Edition and attempting to make it fit canon. They're trying their best, but it's just not compatible, and they're trying to force things back to something they're not. The majority of people playing 4th Edition weren't around for 1st Edition, what Nostalgia are they even trying to bank on? It just isn't working, and it's messing with their system.
The best work Cubicle 7 have produced is when they have creative freedom and they're not limited by trying to mimic other styles. That is why I think Soulbound works better for them.
You could argue that Soulbound evokes images of Scion or Exalted or the WoD games and you may be right, I haven't played those games. But what I do know is that they aren't limited by the legacy of a franchise that's run for decades. They get to make their own mechanics, and when they had the choice, they went for a light crunch, narrative based RPG system with lots of room for creativity and options on the player side, while providing plenty of tools for storytelling. Where they excel is in making something original, because I was astonished at the ridiculous variety of hooks and concepts they made up for Soulbound. Soulbound is very good, and the AoS setting even implemented aspects of the RPG into the Tabletop for 3rd Edition.
Sorry for the impromptu post. Just felt like saying something. I don't want people to get the idea that Cubicle 7 is bad, I think they're great. Fantastic even. I just don't like some of the creative choices they made which limited their ability to contribute to the setting. They really should have let 1st Edition go.
