Also, check if there's any way to access old downloads. If the user previously owned it, maybe on their device, but since app stores remove access, that's not possible now. So, no rescue there.
Wait, does Rock Band Blitz have any legacy? It's based on real band music but couldn't keep the licenses, so the game was forced to close. That's an important point to mention for context. Users might not know that the game was shut down due to licensing issues, which is a common issue in games that rely on licensed content.
Safety is a big concern here. If the user is looking for a direct download link from third-party sites, they could be exposing their devices to malware or phishing attacks. I should emphasize the importance of avoiding those links. Maybe suggest checking the original app stores if the game is available again, but I don't think it is.
Also, I should consider alternatives. Maybe recommend trying other music rhythm games that are available now. Games like Guitar Hero Live, Rock Band 4, or even free apps like Osmo or Smule's apps. That way, the user has legal and safe options.
