Let's see where to start ill try awnsering this to the best without going down a rabbit hole. Yes Destiny 2 is a great game for someone to start or to get into. There are so many reasons I could list on why you should play but im sure you have heard. The game has come a long way and I think starting out is easier then ever before but if you have small guidance because the game can feel overwhelming without even any paid content.
So let's get into the nitty gritty of it. There will always be options and choices for new players to jump into activities or different game modes in this game, people say the game is dying or its dead but its not. I have been gone since after beyond light and ill go into the after effects of why but as a new player if you have people to play with then life will be so much easier in the game. Understanding the classes the weapons the perks the loadouts and stuff will come in time so don't worry about that stuff just enjoy the strikes the campaign that's free then have someone take you on a strike and show you what the characters and weapons are really like and you'll be sucked in.
Now for the part that I think is super toxic about this game. Bungie bungie bungie is very poor at listening to there community also very slow at adding in new content or fixing certain issues the game contains. What I have learned if it gets to point where your not feeling it dont force it let it go destiny 2 can be very very very addicting especially with friends chasing the loot the weapons the hole 9 yards doing harder activities like raids and hard missions like grandmasters.
So down to why I left and came back. I started what over a year ago if not longer now I don't remember I put almost a year into the game of grind love sweat and tears into it and it got stale they were not doing anything to my liking and having stale droughts of no new content that I didn't feel was like in the right direction. Now 3 seasons latter in the game its still not perfect its still the same game just made new changes of life bonus and just making the game less of what I call toxic or more community friendly. I switched to pc and wasn't able to play with my friends anymore on there so I used it as an excuse to step away and play other things but now crossplay is enabled I have actually spoke to friends I have talked to in months and it's so nice.
So here's the thing if you wanna play destiny and you enjoy what your seeing in the first 4 to 8 hours of gameplay give it a chance play with friends go on mission earn rewards and ask questions cuz im sure there are multiple lifers here that will be able to give you the knowledge the know how and the techniques you need to keep going. So flat out awnser is yes play the game only thing I can say is don't let it consume you or let it ruin your mental health because of the bad toxic ways of bungies at times if you want anymore info or why you should play the game I'd be more down to be actually going into full blown details of what the game is all about.
