My review will be condensed into 3 sections. Story, gameplay, and endgame.
Story: Destiny 2 Lightfall story felt more like a montage of learning a new power to use against the antagonist of the story. Though there were nice messages about learning, such as " Flow with the current, not against it." Was the only message that stuck with me. The story was ill comparison to the last expansion Witch Queen. Destiny 2 is currently in their 20th season, and is surprisingly a 6 year old game. Long time fans of the franchise already understand that Destiny story is convoluted, and usually buried in some lore cards usually known as grimore, but personally I just search up lore in YouTube channels such as MyNameIsByf. Lightfall story isn't delivered well, and left me with more questions than answers. After a few days of reading lore I can see the direction of the story, but this isnt acceptable way of delivering a story to an audience In video game. My biggest gripe of Lightfall is how poor the 2 new characters are. Their coverage felt very brief, and didn't really care much for them. Story definitely blended with the gameplay of strand, as the story revolved around the use of strand.
Gameplay: Why change something , when you already good at something? Bungie can make a great fps game. Guns look great and feel great . You can feel how fine tuned this fps is compared to other games. This is their strong suit and surprisingly they can make it work for 31 years.The new super strand has to be used and no if or buts. Story is focused around learning Strand, so that's was the main focus ironically around a super. Bungie invested so much time in making strand and tuning their gameplay. I personally think they focused around gameplay this time around.The new super feels great and fun. Though this time around I felt the campaign still maintened a challenge, and see that player scaling is much better. Though I can see that over time the gameplay can get repetitive and eventually feel boring over time.
Endgame: Funny enough I expected the endgame activities to be difficult but boy I was wrong. Raid content is supposed to be the toughest challenge in the game and be the only content to prepare for. I don't know if it's an illusion of being to experienced at the game that is 6 years old. Perhaps this is the view of long time fans of the franchise. The new raid in my experience was very easy as there aren't many mechanics involved. I could talk about Bungies raid structure for hours. The Root of Nightmares Raid is a great raid for new players of the game. Not so much for veterans since it isn't as challenging, but I understand what Bungie was doing to get more players to do this raid. My only gripe was that every encounter except the 3rd Planets encounter was the same. Heck the last raid boss is basically first encounter with a boss. The only endgame activities I found difficult are the exotic mission in Legendary mode and Legend-higher nightfall activies. Difficulty of raids usually come from the different roles players are responsible for. Since 2 people are required to do mechanics in the new raid people can 3 man a 6 player activity. Usually Bungie has 5-6 players split in doing at most 3 roles. Perhaps this is what the community asked for based on the last non-reprisal raid Vow of The Disciple. Since there are call outs of symbols that can have different interpretations, making the raid difficult. After this expansion i believe Bungie aimed to cater to not just veterans but to newcomers, and returning players of the franchise.
