If you're a Kojima fan then it's a no brainer but gameplay wise, it's unlike anything else really. It's tedious and repetitive but challenging and you decide how to get from point A to B. If you like the Metal Gear Solid series, you can unlock some tools and do the whole stealth/action thing. Story wise, it's very complex and it's not explained in a streamlined fashion. The closest thing I can relate it to, story-telling wise, are shows like Lost and the Leftovers. You don't know what the heck is going on but just enjoy the ride.
It's definitely worth it just for the fact that's it's a unique gaming experience executed masterfully. But games are getting more expensive and $70 USD is tough the spend on a game you're unsure about. If you haven't played the 1st, you should be able to find it cheap second hand. If you have a PC, Epic Games gave away Death Stranding 1 for free for a few days. You never know, that could happen again someday.
