Moving whole Year 1 content to F2P, especially on Steam, gave this game second life. There is plenty of activities you can do with your friends and with daily and weekly bounties there is always something to do, something to discover. Gunplay is great, skills and weapon traits provide an additional layer to building your character and looking for the way you want to play Destiny 2. Definitely worth checking!

UPDATE September 2021

Some time has passed already, sunsetting is also done and new content is landing quite often with bright future shaping on the horizon for Destiny 2.
The current state of the game? From a narrative standpoint, it is superb! Really: most of the seasonal games (GaaS) should learn how to approach plot, reveals, characters, and world-shaping. The last time I had this time with seasonal content was back in the Scarlet days in Guild Wars 2.
Content-wise it is a mixed bag. We are getting new activities, usually something like a horde mode with few steps each of the seasons (the seasonal arenas) and some small instances for fireteams of three. It was some time already since the new Dungeon was introduced (there are currently 3 in the game) and the new raid (Vault of Glass remake) was opened for players.
The last remake of Trials (end-game PvP content) added some life to this part of the game, but there is also a downside - The BattlEye software. Still waiting on the clarification on data collection from Bungie. Adding anti-cheat and not changing tickrate (it is 10 or something) is a little sad, but the priority here was the cheaters, so maybe in the future, we can expect better PvP.

In simple words: I would recommend this game, as there is a lot to do, especially for new and returning players. And there is always that chill and smile when you get your long-awaited god roll (or even exotic item) in your inventory.
