There are tons of games which are overlooked for some reason: they are released at the beginning or end of a console's life cycle, they don't do well with the critics, they are released at crowded times, they are part of limited print runs, etcetera. If you're looking to play catchup, you've come to the right place!
If you would like to submit a game for inclusion on the list, please head over to the forum post. Be sure to read the guidelines in the original post before submitting your candidates.
This list was assembled by me with help from the Giant Bomb community.
