Lol,
That just means you need to be sure about where you 'ahem'...acquire your Copy.
Neverwinter nights is already at final patch stage, 1.69 at least, as far as I am aware, is the latest and final supported version of nwn by bioware.
Your also forgetting that Neverwinter nights is a 'game', and as such, children 'can' be the ones playing it, and they may have saved up their pocket money and all sorts of things to get their original game discs.
Re-investment is not always an option, and in my mind, not necessary.
I am a legal owner of Neverwinter nights, Hordes of the Underdark and Shadows of Undrentide - As such, I will acquire my copies anywhere, anyhow, and anytime I need - and thanks to Bioware's Forums for keeping my CDKey's safe, I will continue to use that methodology. I have no moral quams with this methodology, because I have already given my Cashy Money to Bioware and the retailer. If anything, I am saving the environment by now using/purchasing more game cd's.
Essentially, Im not buying the same thing twice - thats just senseless.
I will say however, that for about a week, I did lose my CD2 of nwn, and as such, I downloaded a cd image, mounted it, just to get past installation, and then found my CD2 again a week later. I was not about to wait 24 hours for the shops to open, to go and buy a new copy of the game, just because one disc was temporarily missing in my tip of a room (yes - I need to clean it but that asside)
The solution was simple for me - wait 24 hours, or go onto some website, and download the disc I was missing which would take 20 minutes.
When I first purchased nwn, I was like 18, unemployed, and no source of income, it was a case of saving up money for me to buy Neverwinter nights - Granted - I am in a very very very good job now, and could go and buy multiple copies of nwn especially considering how cheap it is now, but even on Principle - I bought the game once, im not buying it again.
"Unofficial" copies of NWN are unsupported.
Bioware will 'try' to support us, if we have a genuine CD Key.
They will never refuse service to people who have bought their product.
Granted - Service may be dwindling, and no future patches etc, but they will not point blank say - 'Show me your game disc, I wana make sure you have a real disc before I deal with your support request'.
One thing I would love Bioware to do, is do it like Blizzard Entertainment do it with Battle.net.
You register your CDKey online, and then you can download the game client to your computer.
No quams about lost cd's, scratched cd's etc.
I had a Diablo 2 disc, that was missing, and then discovered that I could download my game client 'legally' via the Battle.Net
If we have supported Bioware, by giving them our money, we dont suddenly become less entitled to service, just because the physical disc is lost under a multitude of clothes and rubbish in your room - because, we dont suddenly stop being their customer.
