While we have all the D&D games from SSI Buck Rogers is still missing. Is there a reason like licensing or is it just that GOG think it wont sell?

I have the same questions about Dungeon Master 1+2.

Buck Rogers should be public domain by now. However that is still being contested right now. So yes, Buck Rogers is still in legal limbo with no resolution in sight.

We don't have all of them. Still missing DragonStrike, Heroes of the Lance, Dragons of Flame, and uhhh... I don't remember if there's anything else.

Chaos Strikes Back too. Though I'm not sure whether that received a PC release.

So the ssi games are still missing quite a backlog? I thought we got the full package in the bundles except Buck? Why not the full package?

Spelljammer: Pirates of Realmspace is also absent

Thanks for that background. Also wanted to point out... Buck Rogers is not technically an AD&D game, it's set in the "25th Century" universe, but uses D&D-like mechanics and a goldbox layout. I always thought, and called it, a D&D Goldbox Game but it's not. Not that it matters, but it might add to the confusion here.

It was the SSI connection and not the D&D connection. It was Only because the D&D and ASD&D games to some extent where already available here on GOG. I Actually did complete the first Bck game on C64 Oor an early pvc back in the day.

Star General's grand not appearing on the list eludes me too you know.....

Sometimes other reasons are at play then the ones labeled as " confusing owner rights "

I still have SG on disc somewhere, and played it again a few years ago. The thing that killed it for me was... you couldn't "lasso" a bunch of ships to get them to ALL go where you wanted... you had to click on each ship and direct them individually to fly to a destination. I just felt like "life's too short" and didn't continue.

But I loved it back in-the-day!

there is also a shareware version available wich works great, i had the most trouble with the lack of a zoom button, the thing that surprised me most was the agressive a.i. - 7 races that indeed react different on war, you have those solitary samurai kittens, those insectoids that go wild the further your advance into their territory, those slave drivers that use human bombs and all guided by an a.i. that is so wild it still even manages to surpass current day modern techniques, such as found in civ 6 for example in some points, tho lacking coherency in the grand design picture
