Want to try to get your favorite vidoe game into the Smithsonian? You’re in luck. Voting has been extended for the Smithsonian American Art Museum’s Art of Video Games exhibition. You now have until April 17 to weigh in on which video games should be considered art.

The exhibit, curated by Past Pixels founder and video game collecter Chris Melissinos, will pick 80 games to include in the museum’s art exhibition.

A spokeswoman for the museum said that more than 3 million voters have weighed in since the site went live in mid-February.

Games are sorted by era, platform and genre, with three games in each genre. Be aware: The voting can be hard. It’s easy to spend an embarassing amount of time deliberating between two of your favorite games when they’re in the same category.

All those who register to vote with a valid e-mail address by the end of the voting period will be the first to know which games make the cut.

Voting closes at midnight on April 17 at artofvideogames.org.
