I've only ever played Myst III, and that is quite enough. The only good part is that you get a nice loooong time to look at the pretty scenery while you're going from one screen to the next. I guess I prefer games with a little mindless hacking and slashing every once in a while, and where you can chat with the villagers for clues (seriously, there is not a single person in the only Age I managed to get to).
