As noted, there's no need to download all of them at once. And I currently have a 320gb Velociraptor as my primary, and 3x1 TB hdd drives for everything else. More than enough space. Any more, you can by 3tb drives for under $100 - everyone's fetish with SSD's seems to have made people forget that spinners work just fine to this day, and they're incredibly inexpensive. As for GOG, you really should look into it. In terms of customer service, they're almost a complete 180 of what Steam is, and that's only because Steam has finally made some improvements. They don't have quite the selection of new games that Steam does, but they do have some of the bigger and better names, and their old game library is second to none.
