Bonk's Revenge shows off what most missed from the Turbo Grafix and is well worth the $6 price tag.
The difference between Bonk's Revenge and the rest of the series is easy to describe. There are more bonus games, well designed levels, hidden items galore, and more/better enemies/bosses. I could just play the bonus levels in this game, they are that fun!!! The bosses fit in with the levels, and the last set of levels do the rest of the game justice, not that oft-too-familiar letdown at the end.
The graphics are pretty good and the levels as detailed as the TurboGrafix ever had. Bonk and his other two forms look good and move good. The music is a treat as well, and the ability to bonk a floret sprung (flower-thingies) into giving up different items is cool. But the main reason why this Bonk is the pinnacle of the series is:
THE SMILEY FACES ACTUALLY DO SOMETHING THEREFORE THEY ARE WORTH COLLECTING!!! The smiley faces are hidden throughout the levels/bonus levels and are added up during play. After a boss is defeated, the smiley faces allow Bonk to gain an area filled with bonuses. These restore health, give extra lives, extra empty hearts, and most importantly, allow you to warp past a whole level. The more smiley faces collected, the better bonus area you are allowed to enter. This is the incentive needed to search for every smiley face and try your best on bonus levels. In other Bonk games, the smiley faces basically have no use other than point value.
If you had a TurboGrafix, then you already bought Bonk's Revenge for VC. If you didn't and you want to know what the TG16 had to offer, than Bonk's Revenge is the best game out for the VC until Parasol Stars and Cadash are released (which maybe never). Bonk's Revenge has the graphics, gameplay, and fun replay value that make it an absolute steal for $6.
