I think Broken Sword 3 is the english version of Baphomets Fluch 3. I´ve also played it because I liked the first parts too. I also thought about buying the new "Myst" game, because I am one of the people who like this games.

But other than this I haven´t played many new Adventure games (but some RPG´s like Gothic & Baldur´s Gate series,very time consuming). And of course I played classics like Grim Fandango,Kyranidas etc.
And for newer Inform etc.-games(some of them I really like) I started Mulldoon Legacy some time ago,but as you mentioned you need a LOT of time and playing it alone is VERY hard. But I think it´s one of the best puzzle-based Inform games ever

. Maybe that I post it sometimes in the ´suggestions´-topic and see if others can be persuaded trying it out with me.
To summarize: After short "flashes" of new commercial adventure games I quickly return to old school text-adventures.
