To be clear I'm not saying it's ideal, just that we don't know the install sizes and actual amount of games generally played concurrently.Depends how many people in the household are sharing the console. 2 or more and that limit might be reached pretty quickly. Personally I tend to have one or two big AAA action/adventure games on the go, a racing game on the side (for the change) and then a library of VR titles for the experience (e.g. having a drink, break out Beat Sabre).
But my wife also has 1 or 2 AAA's on the go at the same time, and as she games way more than I do she's always a few games ahead of me.
Even your situation may be workable without to much problems by the sounds of it (xsx)
But a service like GP could really make trying out and downloading games a lot more prevalent.
Imo still easily a worthy trade of to have ssd.
Out of curiosity how long does 50GB take to copy across a decent usb connection?
Think external storage is going to be even more a thing than it is currently.
Be nice if you could also manage it remotely via app. Feel like playing a game, start it copying before even get home etc.
