I'm glad you see what they're going for.
As to why it looked like that mere months before it's planned launch, horrible mismanagement, only thing that makes sense. Or maybe COVID just impacted their schedule that significantly.
As to the gameplay side, I don't think that's fully shown yet. Remember this game has upgrades, so it seems there's a new pseudo RPG feel to go with its psedu open world approach. We shall see.
I still maintain to this day that if I can't dive out of a pelican battle royale style during campaign I'll see that as a huge missed opportunity.
