"OK, so I know that you two are always arguing about what type of crosswords to do-
'Normal crosswords are too boring!' 'Cryptics are too esoteric!!'
Trivia vs wordplay, yeah, I've heard both sides. But, I've also heard that you BOTH love video games, so here's what I've done:

Here are twenty crossword clues that describe twenty video games. Solve them if you'd like!
OR, if you treat each clue as cryptic wordplay (without a def) instead, you'll find a different video game as the answer for each clue!

Why don't you two work together for once, and when you get all forty written down, you can put the highlighted letters together to get one last clue. Which type of clue is that one? You'll see!"
