Remember when Google announced on I/O 2012 game streaming using Gaikai service which was acquired by Sony in 2012 and eventually became Playstation Now? ;)
... I want something like Netflix for games. To pay a small monthly fee (or pay per play) where you can simply select a game and start playing. No purchases, downloads, maintenance etc. And don't underestimate the fact that all you'll need is browser. This can bring gaming to much (several times) wider audience.
