Well...Peter Smith has a great point!
Linear can mean different things! And reading the comments, I think what I actually like is linear in the way that you can not progress untill you have done certain things in order! For this reason, I;m not a big fan of MYST, etc...I like going somewhere and not being able to leave untill I have done all there is to be done.
For example, in Black Mirror and Still LIfe...you could not leave untill whatever needed to be done, was done!
I get too frustrated with going from place to place and back again and all over and there agin! I like that I'm limited to a few places or even one place, that I must find that one thing to continue!
Does that make any sense?
