It's always nice to be able to take your save with you to friends' houses, traveling, or even just to your couch/bed without lugging your computer everywhere (or worrying about copying/syncing saves across devices), or just play your desktop-quality games on a phone/laptop while sitting somewhere comfy. I have two dedicated gaming computers (one at a desk and one at a TV) and apparently still ended up putting in 828 hours of Stadia because it was just a nicer experience to have a single "gaming PC" with all of my games/saves that I could access from anywhere (even from either of my "real" gaming PCs!).
