Super Bonk (Bonk "4") is old news.... Not exactly an obscure game, came out back in the day, even in the U.S. It's by FAR my least favorite of the 5 16-bit console Bonk games. Seems to me people that don't like Bonk 3 would, on principle alone, absolutely despise part 4 since it's all the the things people complain about 3 and more... I say this only for people who've never played it, are thinking about picking it up, and already know they don't like 3.
Personally, I don't like it because it (in my opinion) lacks any sort of individuality, is very bland visually and has that lifeless SNES synth sound to the audio. It feels like a cheap attempt to cash-in on Bonk's popularity on a more popular platform.
If you weren't aware of this game, then there's absolutely zero chance you're aware of a fifth game in the series-- Super Bonk 2, also on the SNES, although it's the only console Bonk that didn't come out in the U.S. I don't know if it's available on the VC (probably not), but it's better than both Revenge and 4 as far as I'm concerned. They really went back to the drawing board with SB2 which, let's face it, was desperately needed after the four previous games were more or less cut from the same mould.
