I played a lot of Destiny 1 (including all the expansions) and I played Destiny 2 quite intensively at launch - until the second Iron Banner, I think.
After that, I just gave up. I know I wasn't alone in doing that; the dearth of content was particularly bad around that time, and realistically all I could do was run a few missions a week because of the way the light system was structured.
It sounds like things have changed in a positive way, but as someone who only owns base Destiny 2 digitally, how do I even go about getting back into it now? Do I grab the F2P version? Do I re-download what I already have?
