Punky, you haven't seen the arcade-, or the Atari 5200-versions? Or the C64 version? Pretty much all Frogger versions are good, but to say that this version is THE BEST makes one only think that you haven't seen all the versions as of yet.
Can you at least elaborate; WHAT in your opinion makes this version the best that you have seen? (How about 'you have heard' or 'you have played' or 'you have experienced'? Are those different?)
A good Frogger, nothing wrong with it - but it's difficult to make Frogger into somethign bad. Heck, even the Apple II-version is a great game!
