Is there a way to get access to a deeper body of games using the opening explorer? Are we limited to only the few chosen as "top games"?
Go to the settings icon after clicking on the book and choose "lichess" this gives you access to lichess games as opposed to masters if you mean other otb games then honestly idk
For example... if I move through the opening moves and get to a spot where it shows 150 games were played with that position, it will only show 4 games. With Lichess selected it shows 4 top games and 4 Lichess games. On chess.com's opening explorer you get a multipage list of all 150 games to view.
