About mid-2007 some of these games were mysteriously removed - Super Mario RPG, Kirby's Dream Land 3, Zombies Ate My Neighbors and Duck Hunt were all rated for VC one day and were gone the next. Super Mario RPG and Kirby's Dream Land 3 have of course since been rerated and actually released on the VC.
Yesterday the ESRB decided to remove more games which have been rated since the Wii came out - Aerofighters Assault, Beetle Adventure Racing, Hagane: The Final Conflict, Tin Star and Uniracers are now all gone. Sadly this probably indicates that they're not coming out on the VC anytime soon, so to reflect this, we've removed them from the site for now!
This also means there's now only two games left which have been on the ESRB since the Wii came out - Pilotwings and Pro Wrestling. Both of these games are by Nintendo, so there's almost no doubt they'll be released eventually, but it's a bit worrying that every single other game rated since launch is now gone.
