Adding more options doesn't mean worse performance. Adding the ability to have a game unrated doesn't hurt anything... when the game is created, the only thing that would be different is the fact that a flag is set as unrated vs rated. Adding extra options on the games page so that you can "make move and go to certain page" doesn't affect performance, in fact, it should help, since you can get to pages faster without going through more clicks, which means more database queries and more pages to show.
