Both have their pros and cons. 15 minutes can be great or extremely bad. 10 minutes can be extremely quick and seem to have lackluster endings. Blah blah blah<br /><br />I&#039;ll go with this: 10 minutes gets more games played and gives others more opportunities to play. I&#039;m not totally in favor of 15 minutes but I&#039;ll stick with 10 because of just that.
