No Heart of China? Je pense que non.
I'd like to agree with you, but I actually feel that even though the setting were awesome (Asia in the 1930s, a gamification of the Adventure movie genre, so on) it wasn't actually a terribly good game.
A bit of a problem in general with Dynamix' adventure output, the usual had really good settings, but the execution was a bit meh, or maybe forgettable is a better word, since it seems they were all pretty much forgotten
Toonstruck occupies a weird nostalgia space for hardcore adventure gamers, as does Buried in Time - Toonstruck possibly because of its "incomplete" status and Buried In Time... I just don't know (I have a very low tolerance for 1st person adventures, though, outside of Zork Nemesis and Grand Inquisitor). The Dig being more mainstream and seen as something of a "disappointment" in comparison with the other LEC adventures probably has something to do with its relatively low ranking - that's the basic reason they've given in the write-up for the list, anyway.
I don't think it's purely nostalgia. I recently replayed Toonstruck, and actually really enjoyed it, it's still awesomely wacky in my opinion, but I do think it's the kind of game that you either like thoroughly or hate.
The Dig
was a disappointment compared to LEC's normal high standard. It was a kinda bland mix between Indiana Jones and Lost in Space that was technically good, but lacked memorable moments and characters, if it had not been made by LEC, it would not even be on that list. Beautiful music though.
I remember when Longest Journey came out PC Gamer UK gave it a score in the 70s that was seen as something of an outcry!
Another game I recently replayed. I loved this when it first came out, this time around I was bored to tears...
I'm glad to see The Last Express being so high on the list. It seems to have been given something of a revival in recent years, not least thanks to GOG. It's such a shame that it never got the success it deserved when it came out. Another game that is deservedly getting a lot of love is Blade Runner. One of the best Movie -> Game adaptations ever.
