I think the general advice I can offer recent Unreal layoff folks is that, your severance looked a lot like what they gave us at LEGO, and:
1.) You'll probs never see that in your career again
2.) It's the best runway to (indie / your own business / etc) you'll ever be handed, so use it if you can
Doesn't mean you gotta jump indie, that's risky, just- ANY business idea you've had. Any big life-changing thing that requires some runway. You're probably never going to be handed a better opportunity to execute on it, so think really hard about if now's the time, and maybe go for it.
