I have added 2 Steam and 1 GOG game libraries to my HLTB account. Then I have categorized the games based on completion/pad controller usage etc.

Afterwards due to long backlog of games I have sorted the list by main story completion time from the shortest and began playing one by one. Of course not all are worthy/interesting enough to finish, but most are.

Having the list and the goal of going through these titles let me focus what I already have instead of grabbing another title, which will stay in library for the next months or years.

Also you wont have to worry about new releases, because you have already something to finish with certain goal in mind, will effortlessly wait until the price drops significantly with nice cut, all dlcs, packed in Limited/Definitive/GOTY edition.
