Where Steam fits
Choose it when the games you own or want to play are distributed through Steam.
Check before you choose
Check each game's operating-system requirements and available storage before downloading.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
A launcher manages a library, while a game or emulator has its own requirements. Check edition compatibility and account ownership before coordinating a shared game with friends.
