The Box Escape Game Metz: Casse du Siècle

The game is originally in French and live, but the translation to English and online is superb.  These guys did more than just adapt a few puzzles to online play; many of the real room puzzles have been replaced and supplanted with several experiences and challenges that can only be done online, meaning that you don't come out of this feeling "boy, that was a pretty good room but I bet it's even more fun in real life."  The avatar character is a pretty standard "clueless hapless piece of meat" that many of these avatar rooms have, but here Bob (that's his name) also has a few enthusiastic aspects and quirks that makes him a memorable character -- for example, the sections where Bob gets phone call on his cell and therefore stops listening to you when he's on the call feels like it should be infuriating, but actually added to the immersion and charm for me.  The new stuff isn't for everyone -- I can imagine some teams finding one challenge near the end tedious and frustrating -- but it worked very well for my entertainment.
