This is a great value. I started collecting some PC-Engine games a few years back, and it gets expensive pretty quickly. I know some people aren't happy with the line up, but hey, that's what modding is for.
It is said the TurboGrafx was released in the UK, probably limited I'm guessing. I know a few years ago I seen one of the "console repair" youtubers work on one (which was labeled a "TurboGrafx" and not "TurboGrafx-16", that small distinction between a UK console and a US console.)
It was kind of released. Basically a few (could even be the one) mail order company got the blessing to sell consoles into the UK. However there was no official UK console, the consoles were imported and modded to work at 50Hz and with the power supply in Europe. Was probably the same in France.
