@retrohistories Eric Chahi's Le Pacte is a good one, it was his adventure game right before Another World. Despite the author's notoriety, that game remains in French only and only released on CPC. So... yeah. But I did play it on Twitch recently and it was pretty interesting.
Armed & Delirious (aka Dementia) is also a pretty good example in that it is a ... uh unique adventure game but it would be almost impossible to re-release it today.
