Got the idea from letshugbro who got the idea from like three other people so I'll just link his list here: https://www.backloggd.com/u/letshugbro/list/the-iceberg/

Sorted my Played Games list by popularity and picked 5 favorites from each page, except for the last page where I ran out of real games so there's only 2 there. Tried to stick to actual games and not DLCs/expansions or enhanced ports/remakes (though there are a few of those in there)
