Chromebooks have hard disks (or more usually SSDs) so they can cache that data. Also, would it not make more sense to automatically download parts of that 10GB of game data if/when you actually need it, rather than leaving it sitting on your hard disk? With today's broadband speeds that shouldn't be a problem.
