I made this quiz yesterday:
http://www.sporcle.com/games/jacehan/one-letter-off-countries
At first I put it in Just For Fun, because it uses word play. But then I moved it to Geography, because it has a lot of geo knowledge. But then maybe it should be in Miscellaneous? I dunno.
I also wasn't sure about a title that best describes it the way the puzzle works.
Also, if you do look at it, I feel like most of my clueing is fine but one or two are iffy - if you have suggestions for rewording or alternate answers, that would be great. Thanks!
