And the game is out! Has anyone else played it yet?
On a (fairly underpowered) Windows XP machine, the cursor is a bit laggy and the game choked on the opening cutscene, but apart from that it's pretty glorious. The graphics are just as excellent as they look in screenshots, the voices fit great, and the music (new and old) is superb. The game is its old award-winning self so far, with just a couple of little changes to the puzzles.
I got it through GamersGate, and have to say the whole purchasing/download process was a bit painful. But it was worth it in the end!
