If you talking about the OG Crisis then its simply because they had a roster of creatives with an interest in the material, that were (relatively) recently freed from censorious restrictions but still had company obligations to work within.
On top of this they had a ton of material to both draw upon and build off of without allowing many petty fanboy hang-ups of "not muh childhood" warp the work. Like with what would happen in the future.
In other words it was the right talent at the right time in the right place lacking just enough ego while having the resources to make it all work.
