Games you already bought
The alternative is paying for hardware, so that point is irrelevant. It’s essentially a hardware rental service. If you play an hour a day every day, that’s only $146 a year. I’m lucky if I get to play 2 hours a week, with that comparison this is technically a better value than my gaming PC or Steam Deck.
Obviously there’s a lot those devices can do that cloud streaming can’t, but this ultimately makes gaming far more accessible. Got a friend you want to play games with but can’t convince them to spend $600+ on hardware? This is a much better value proposition that gets their foot in the door.
Still, I don’t like the implications for a possible future where hardware is outrageously priced and largely inaccessible.
