Feedback from a 16 year old casual gamer

[Redeemer]

I have no interest in playing any RPG that takes longer than 24 hours of continuous playing time to beat. Remember, I'm a CASUAL gamer.

Now about Riven... I've never beat it myself, but I've seen my brother beat it. I've seen the best ending, where Ghen is captured, Atrus is reunited with Catherine, the people of Riven are evacuated, and Riven is destroyed. That was always a great ending, but I still wonder, how is it physically possible for you to fall out of a planet through the ground? Is the world inside out?
