The ESRB website has updated once again, and a few surprises are in store for Konami fans. Two of them originally were released on the NES (Castlevania and Teenage Mutant Ninja Turtles) and two came out for the SNES (Gradius III and Zombies Ate My Neighbors).
No idea when these will be out, but hopefully it's soon. All four are wonderful examples of their particular genres. I'll probably be passing on all but Castlevania at the start, though I distinctly remember having a blast with Zombies Ate My Neighbors back in the day, so who knows?
By the way, Nintendo, I'm still waiting on Duck Hunt, Excitebike, Metroid and Punch Out!! (among many others)--just in case you're listening.
