A YouTube user by the name of CryptoPunk has uploaded a tutorial about AWStats.io - a sort of visual data-mining tool which you can use to explore who is getting good drops from Alien Worlds, what sort of a deal landowners are getting and what tools are successfully landing legendary NFT's.
Here's the video and here's the website which he mentions.
The video implies that you don't need mega-expensive tools to get good drops. I'm still figuring out how to use the tool and I'll update on this next week.
