I`m not totally clued up on Steam, as it`s always sounded a bizarre way of doing things unnecessarily and stayed as far as possible from it. Sure some games have installed with it, but I`ve tended to block the upd8 and auto-stuff as much as I can.
But, if u get something through Steam, and I correct in thinking, with this in mind, that u can log into it on any computer and download whatever u have already purchased as many times as u like ? Otherwize, why would u want ur setting preference to travel with u.
To that extent; buy something, set it up on ur pc. Goto ur "brothers" pc (that u installed OS) and download the same thing ?
Cept u would be arguing over settings ?
Seems weird to me, or I`m not understanding downloading games through steam.
