Cyan promotes Riven right.
The team recently released a beautiful trailer of their full remake of Riven:
And aside from a momentary teaser, this is the only typically-formed trailer they've published, and the only one they intend to publish, before release.
Instead, they've been promoting the game with simple, quiet moments from its locations:
It's hard to overstate how right that feels. This is a small, long-lived company that, decades later, knows where its soul is, understands what their players love about their work, and puts that first.
Even if you have no idea what Riven is, those clips tell you with stark honesty what you're going to get: beauty, mystery, nature, autonomy, and no hurry. If you're an expert, then each clip subtly tests your memory and hints that there's more to this version of the game than you remember.
The original version of Riven is nearing three decades old, and even the graphics and sound of that version exceed the quality (if not the fidelity) of the average game today. And the remake blows that out of the sometimes slightly curiously-behaving water.
