Like any good Bonk--or, PC Genjin, as he's called in Japan--fan, I consider the character's PC Engine outings to be (basically) the only ones worth my attention. As a result, I've ignored pretty much all of the spin-offs that have been released for the GameBoy, the Famicom and the Super Famicom--I'm just going to ignore the later atrocities--over the years.
Artist and blogger Curtis Bathurst seems to share my interest in BC Kid, at least as far as the game's aesthetics are concerned. In a recent post, Bathurst critiques the game's promotional art (right) as well as its in-game graphics.
Although he isn't a big fan of either, he ends his post on a positive note saying, "I find it wildly exciting that there was ever a coin-op Bonk’s Adventure and I love rummaging through the ‘net in search of bits and scraps about the game."
If you're at all interested in graphic design--especially as it relates to the world of gaming--I highly recommend heading over to Bathurst's site and reading his post about this quirky quarter-muncher.
