Frogger was an odd release that came out during the last gasps of Sega Genesis' life (1998). It's a port of the arcade game (not the "new" Frogger that came out on Playstation), so if you've played that you've played this. You try to get your frog across a highway and a river 5 times, each time filling up one of the holes at the top. if you hit a car or fall into the water, you lose a life. Simple, much like other arcade games.
Now, the Genesis port (unlike others before it) is arcade perfect in every way. All the music, graphics, and gameplay are preserved perfectly here, giving arcade-lovers reason to celebrate. The only gripe (and one that could easily be remedied) is that the Genesis pad isn't the best out there, especially for twitch action games like this. So, if you've got a Genesis, a good controller, and a craving for some home Frogger, you can't get any better than this.
