I thought 'The Kung Fu' (sorry I have to wash out my mouth after saying some of the cringeworthy TG-16 renames) was a pretty mediocre title at best, until I found out it was the 1st ever pcengine game released.
It is probably on par with Tekken1 on PS1 for showcasing the hardware, not the best gameplay ever but a showcase of the graphical capabilities. Both machines were pushed way beyond previous generations and what these games showed, respect.
Otherwise it would have been football to the groin!
