I haven't posted one of these since the Gameshelf got its stylish new (that is, Greek antiquarian) logo. But the fanboy I remain, so here's what Cyan has been whispering:
Riven for iPhone/iPad/etc is marked as "coming soon". Riven is my favorite of the series, but I haven't played it since its original release -- it's notably hard to get running on modern machines. (Even harder than Myst, which has been updated and re-implemented all over the place.) I am seriously looking forward to this one.
Cyan also pushed a stack of games up on Steam. But if you use Steam, you probably saw that.
And finally, this teaser page was linked from Cyan's home page today (although I don't see it there now). The banner tag was "Never Let Your Timbers Be Shivered." What is it? Looks like some kind of resource-based explore-and-fight. With pirates. That's all we know -- except that a Cyan folk also dropped into a forum thread and linked to this MP3 file.
