Forget DVD extras or merchandise - the real way to cash in on movie blockbusters is through video games. Movie-themed games are driving substantial purchase interest among gamers, according to Monday data from Nielsen.

Gamers were polled about games they were definitely or probably interested in buying, and X-Men Origins: Wolverine topped the list, followed by Goldfather II and Transformers: Revenge of the Fallen, all of which were released in the last few months.

In terms of games that have received the most online buzz for the past 60 days, Ghostbusters: The Video Game easily topped the list. Terminator Salvation and Wolverine rounded out the top three.

"Nearly a quarter of all movie-related video game buzz over the last 60 days is attributed to Ghostbusters, which was released on June 16," Nielsen wrote in a blog post.

Games geared toward younger games like the Hannah Montana, Night at the Museum, and Ice Age games generated less buzz than their more adult-themed, blockbuster counterparts, Nielsen found.
