I own both versions of Starfleet Academy and I was able to run them both. Sadly the DVD version isn't that great after all. It was one of the first game using mpeg2 cutscenes and the quality was worse than the CD movies. No anamorphic video and color bleeding combined with less sharpness :( So, IMO not worth it. Stick to the disc version.
Interesting I got both original CD and the DVD version also.
What operating system did you use to do the comparison of both versions?
After downloading and installing, the visuals seem almost in-line with the CD-ROM copy and are almost exactly as I remember them. The game does however come pre-patched to 1.15, which has the shield indicator and other features that were implemented in that patch.
The game does not come with Chekov's Lost Missions, but hopefully that'll be a free add-on later.
Bummer. Well I hope GoG can get their hands on the DVD version and are able to make it work. It's as rare as hen's teeth, but given the game's focus on video, having it in DVD quality would be really nice.
I don't know if it really is "that" rare but I got a DVD version. I don't know if GOG can get an ISO of mine for updating the CD version on GOG. Or if they can only do it directly with whomever owns the rights to the game now.
