I noticed that some participants in the 24 hour competition chose to present their game using landscape orientation ("paper on the side"). Do you feel there are any advantages to use this format over portrait? Or is it just an aesthetic choice?
Another thing I was thinking about is the paper size. Being a Swede I work in A4 by default, but what about using a square format for instance? Should the paper size reflect the designer's artistic point of view, or (since I'm thinking about free RPGs now) should it be made as easy as possible for the end user (that is, a format that he/she can print without hassle at home)?
