(that said, some of Cyan's "Ages" don't really fit themselves, such as the spyroom. But since it's more like a linking hub, it's ok for me)
About this new realMyst: I'm really amazed to see Myst Ages on such engine, but I have to agree some models and textures still do not fit at all. For instance, in Mechanical, if you remove the sky, shadows, sea... well, everything handled by the engine... it's horrible !

About Channelwood: it still feels a bit unfinished (for instance, no ripples around the trees), but otherwise I think the lighting really fits.
Man, it looks like they even used this sunshaft shader... too cool !
Finally, the Myst island... It's nice, but it's a bit too welcoming to my mind. Too lushy-greeny. Somehow I liked the almost barren island from the original game, with the dense mist everywhere. Plus the way the stone blends into grass is crap IMO.
Based on Plasma ?tachzusamm wrote:Besides that, I guess (though I can't know) that Cyan does not really develop a completely new, revolutionary game engine. My assumption is that it's still based in many points on plasma.
You mean, this would be running on an upgraded Plasma engine ? With new distortion, sunshafts, bloom etc shaders ?
Plasma is years behind the current engines. I doubt Cyan has the resources to upgrade Plasma.
They used Unity (IIRC) for the iPad version of the game. I rather think they are using another game engine again.
