I've been going through about 20 non-adult games (Moshi Monsters, Bin Weevils, Secret Builders, Club Penguin etc) for my 6yo to see which she likes, the ones which you have to download are always a fail one way or another, whereas the ones that ended up with some money from us were easy to play and sign up to in the browser, and withheld enough game features to make you want to upgrade.
