DoomSooth: I believe Sony owns Psygnosis. If they do, you can probably forget about any of their better games showing up DRM-free. There's a grand total of one Psygnosis game here. The other place has it, too, and it's the only one.
neumi5694: That has no much to do with Psygnosis in the first place, I think. The publisher Psygnosis is dead for good. We won't get anything from their side.
The developers from Piko Entertainment (they made the one Psygnosis game that can be found here) however released over 20 of their games here.
Since Impressions Games - the developers of the named game - also released several games here, there is a chance.
DoomSooth had the right idea -- Sony has apparently maintained Psygnosis as both a legal entity and active trademark, despite not having used it for anything much. I would imagine that means that they still own some of the titles that Psygnosis/Studio Liverpool did before its closure. However, I don't see any mention of Psygnosis publishing Impressions'
Global Domination -- both on MobyGames and Wikipedia, it's listed as having been self-published (which seems to have been the case for a lot of Impressions games before Sierra bought them); so, if Psygnosis ever published that game, it was probably only in specific markets.
But! Impressions Games has been defunct since 2004, and its main staff scattered. (The studio that seems to have most closely succeeded them, Tilted Mill, also seems to have been unofficially dead for years now.) Impressions' founder, David Lester, doesn't even seem to have been active in the games industry in at least twenty years. All but one of the Impressions-developed games sold here were from the era when they were owned by Sierra, and the one that's not (
Caesar) is from a franchise that only got huge after they took over, so it's likely they had acquired all rights to that. But the old Sierra was itself closed down many years ago, a lot of its assets probably sold off (Rebellion bought the
Lords of the Realm and
Lords of Magic IPs that Impressions worked on, for example). Sooo...
...Basically, who the hell knows who might own the rights to a lot of those Impressions games that have never been sold legally as downloadable titles. :)
