In the steam games list. Not that I'm saying a well organized game folder structure is bad though.
Where exactly? Inside a folder in Steam? I've been doing that all my life inside a folder named Games on C:
Obviously I meant you don't need to have a CD/DVD in the CD/DVD Rom to play it as most games today requires. Luckily there seems to be a trend to remove this (thanks Blizzard for your latest SC/War3 patches :) ). As for the actual game data you can redownload from Steam any time you want on any computer you like so you're not screwed if your computer dies. I've also seen a backup option on Steam. Never tried it so I'm not sure what it does but my guess is it backs up savegames and similar.
Err... I don't get it. You trust your HD to the point of not making CD/DVD backups of software you buy online? And if space is the issue... well, with only a few exceptions where I want to keep the box when I think it will become a valuable asset later (did you know for instance that someone once offered me 2,000 USD for my Eye of the Beholder trilogy originals? Can you get that from a download?), I trash boxes and even jewel cases. I keep the CD/DVDs on a rather convenient and easily storable multi-CD briefcase.
If that's the case you can disable autopatching
Ah! As if I would trust game patches the day they were launched. As if we all didn't quickly learn the word "rollback" at least once in our lives. No, thank you. I want to take control of my machine and the software I have inside. That means manual patching. But, most important, you are right. It may mean something to some people who simply don't want to bother and just see their games update automatically. But offline distribution can also guarantee auto-patching. No news there.
It took at most 20 mins from when I first heard of ID's super pack (all quake/doom/wolfenstein/keen/hexen games in one chunk) to when I started playing Quake1. If that's a good thing can be discussed :).
Subjective to say the least. 4 GBs, 5 minutes later? In your dreams on the vast majority of the world. A 15 minute drive gets me a game that takes 4 days to download on the vast majority of people computers and, on most cases, may break their connection downstream limit and gift them with an interesting internet bill come the end of the month.
I definitely wouldn't bring my game CD's to work, that's for sure...
err... And? You can't do that otherwise?
