Some of the best selling movies in the past couple of years were video game ones: Mario, Minecraft, Mario Galaxy were all huge. All close to or over a billion dollars at the box office. The Sonic films were popular, and Detective Pikachu was decent.
The new Mortal Kombat ones did pretty well, but I prefer the original.
Honestly, video game films have been outperforming super heroes for the past several years, though Spider-Man turned that around.
