And, to add something to the more games argument: Rockbox is about playing music. Not playing games. While game plugins are nice it's not the focus of the devs to increase the number of games in SVN and thus increase the number of plugins that need to get maintained. (Of course, if a dev likes a game plugin, wants to include it and does the required work to make it good enough for svn there isn't anything against it, but it simply isn't the main focus.)
