I’ll cover this in more detail over on GameSetWatch later, but some people here may be interested in Emerald City Confidential, Dave Gilbert’s new graphical adventure with a film-noir take on Oz. Though it’s marketed through PlayFirst, it’s a lot less casual and a lot more adventure than most of their other offerings. The puzzles tend toward the easy side, but they’re fun and generally fair (and there are built-in hints, so you probably won’t spend too much time stuck).
I did run into a couple of surprising bugs in the late game, which I hope will get patched for a future release. But even counting that into the experience, not bad.

Oh *that* Oz. I spent half the demo thinking, “But what does this have to do with Australia?”
