[quote name='elessar123']Digital games, including GOG DRM-free games, are single user, not single computer. So technically, you do need one copy per person playing, so there's nothing wrong with multiple accounts, one per kid.
If they change the laws to allow digital licenses to be resold, like they are doing in Europe, then you have an argument.[/QUOTE]
[quote name='anarchyoblivion']I highly doubt that the Steam Box will allow multiple people to access a single account at one time. Much like when Netflix boots you off for streaming too many devices, Steam will boot you off the Steambox if the same account is logged in elsewhere. Valve is pretty strict on their single license, single user (same user), policy; it's also clearly stated in the TOS. In the end, you purchased a license to play a game only for you and that's it. Even giving your account to somebody after you died is breaking the TOS.[/QUOTE]
To both of you, just because a clause is in the terms of service does not mean that it would stand up in court.
Regarding steambox, it is Valve's entry into the holy of hollies (stuff that hooks up to your TV)j. I imagine they would at least rig it similar to steam on mobile (e.g. Android App) where you can be logged into it while one computer is. I am not sure they'd let you play two games simultaneous, but a living room entry has a different use model and needs to be treated differently than some PC desktop.
