It appears that eventually all of the Parasite Eve titles will be available to play soon enough on modern day consoles. The ESRB has given a rating to Parasite Eve 2 on the PSP and the PlayStation 3 which is the same exact thing that happened with the first Parasite Eve before it was revealed to be set for a re-release.
The rating doesn’t go into any detail about the game itself besides providing an M rating. Also if you pay attention to the two ratings from the original release and the current, they dropped the “animated” part of violence and gore. I suppose back then things used to be considered a lot more animated than they are today. It’ll be interesting to see how long it will take before Square Enix confirms their intentions for Parasite Eve 2.
