I understand your frustration uk_john and I too at first thought it was unfair that I had the CD retail version and had to purchase a download edition to get the latest version.
I then realised what a jerk I was being.
But please let me explain a couple of points.
First:
the cost involved is a few bucks. I have bought games for $100 and they have been duds.
The cost for this downloaded version is very cheap.
Second:
The digital version is a re-released version. It is not the original that has been patched. For example the original did not have widescreen support. Widescreen was not used by the majority of gamers back then.
This version does however support widescreen.
Perhaps the developers could have spent more time working on a patch for the original retail version.
But considering the years that have passed since DD was first released and to now when the digital version was released, I hardly think Larian could devote resources to a patch. The digital download version helps pay for its development.
If you really feel the need to have what the digital version offers, then just pay the $5 it costs on Impulse.
If not then you can still enjoy the original.
This is a very old game. The fact that it is still being supported in some way I think deserves praise.
And not the whinging you are posting about.
