Was in the Steam sale recently - bought it, completed it. It's pretty good - revisits a lot of MI1 and 2 with the hindsight that comes with age. There's a lot to like, but it's also fairly blatantly unfinished, some of the puzzles seem like placeholders for the much bigger puzzles that ought to be there, if you see what I mean?

It's not quite as good as any of the original trilogy, but it's not far off. Massively better than 4, obviously. I quite enjoyed the Telltale ones, tho - the episodic structure forced them to keep the puzzles tight, and they had some really good moments.

The post telltale one is a return to form.
