RetroPie's interface is customizable, and there are more than enough customization tweaks to make your interface look and feel unique. This is a fan-favorite for many since it has just about every emulator built in, thanks to working in tandem with RetroArch and others to provide emulators. If you're looking to create a retro gaming console with one of the best Raspberry Pi controllers and an emulator, arguably the first place you'll stop is RetroPie.
