I saw a good video on extra credits about this a while ago. Essentially there's two approaches you can take when licencing your property.
1) sparingly, and try to ensure every single use of the licence is amazing. This is hard to do well because of how broad the warhammer IP is. So many things to explore and so many systems and mechanics. It can cost a lot of money to do well. Large time between games limits exposure. But if you have a hit, it's a AAA hit.
2) like a shotgun, throw it to whomever you want. Cheap to do, but risky because you are hoping for a lucky break with one of them. Works well for their IP because there are so many distinct slices they can divvy out.
Back in the day, GW used to go with #1. You barely ever saw a warhammer game.
In the recent years, some time around DoW2, they changed tact. Giving many, many devs access to a tiny tiny fragment of the IP. The idea is that you push out so many games that that alone gives you great exposure. And ultimately the internet and people have short memories, so if you release a flop (there was a snotling slingshot game at one point.. https://play.google.com/store/apps/details?id=com.wickedwitch.snotling), people will forget about it. If you're lucky you might get a real success out of it.
I think this was the video I was thinking of: https://youtu.be/GOVrmfXolQg
It wasn't a big hit but my studio made Snotling Fling. One of the shots is the Doom Diver and I thought it was pretty fun :)
