Real time puzzler

I'm kinda bored and I feel like playing a puzzle game - like myst but a real time game. Can anybody think of any challenging puzzle games played in real time other than myst 5? Thanks

o-- Star Ship Titanic

They're all like Myst (adventure; point-and-click type)

agreed, one of the best games ever. impossible not to enjoy! unfortunately there's a glitch which makes it hard to complete on pc's with newer processors.

WHEN will they update it!? :shake:
