yes, but none look as impressive as ADAM series. The makers of the engine should show what their engine is capable of doing when you use it "adequately", in an actual game.
Everyone can make tech demos, but to actually having an impressive looking game is a very different thing.
because the Adam series has been designed to work as a short story, and not an actual video game.
To use it as well as they do, you'd have to be on their level of knowledge and have a lot of money, not to mention an idea for what could be a good looking and good playing game.
It still hasn't stopped me from appreciating what these guys have done with just a demo though.
