Online Trivia Games That AREN'T Multiple Choice

Every so often I’ll get in the habit of playing online Jeopardy! or NTS trivia. For both of those games, however, you are confined to picking multiple-choice answers. Because of this, the games feel a little too easy and get boring pretty quickly. I’d really like to find a free online trivia game where you type and submit your own answers. Are there any good ones you know about that fit this format? I like pop culture the most, particularly music and movies, but I’m willing to play academic or general knowledge as well.
