Steam is moving around now.
Steam is moving around now.
If I want to play my Steam games at a friend's house, do I need all the games and the software to be on an extra drive, or just the game files and saved data?
You're right to worry about that. If your games just store save data locally on your computer instead of on the cloud, then Steam won't be able to read them automatically. You'd need to copy the saves to a folder you can easily find or use another program to move them around.
