When I was younger and the videos games were limited to the PC, I remember there were many videos that had a oceanography theme. Ocean Explorers was one of my favorites. There were even games that identified the marine life with real videos of the sea mammals and fish.
Nowadays the video game industry has done very little in the way of really fun educational games. The math games are boring and when it comes to biology you can forget it....there is nothing.....nothing for the ps3, nothing for the xbox and not even anything for the PC. I wonder why blood and violence sells or maybe it doesn't but that is all there is being offered.
