Returning player with no idea what to do

I played D1 religiously through the entirety of the game, but struggled to get in to D2 and only played it for the first year or two.

I’ve now decided to redownload it after all the buzz online about the final update etc.

It seems like there’s an overwhelming amount of content and I have no idea where to even start.

Wtf do I do? What story/quests do I even start with? Is there even any point in coming back to it now? What should I be focusing on?

Any advice would be much appreciated.

Thanks
