"Frogger Returns boasts a game 12 times the size of the original..."
How's George ever going to get it off the street to keep his high score!?
Seriously? I've played Frogger. I've played the Frogger on the PS1 that's featured at the top of this page. In my opinion, it wasn't any more fun than the original. Unsurprisingly, the screen shots really do look like more of the same. If you enjoy Frogger, it's for you. If you don't, I'd doubt there's anything really here that would change your mind.
Also, 12 times the size of the original? How are they quantifying? 11 more stages? 12 times the number of spaces to jump on? 12 times as much memory? That's probably the most vague number given to describe a video game I've ever seen!
