Sonic has multiple games, Shadow has his own, so why not finish up the hedgehog trio দ্বারা making Silver a game? Sonic Team is probably putting that in mind and thinking about a good story for Silver. Also, Silver doesn't really have any backstory to him, and it'd be cool to see his past.
I think a Silver video game would be super cool! Especially because they could make it futuristic and sci-fi-ish. Maybe even have spaceships in it. Although that would just be an extra thing and not the main point. But it could have super cool technology and space-like environments.
