So an update for anyone that is bothered. I have now played the console and gone through its various menus and quickly played the games it came with.
First off... the console is really well made, well impressed with the build quality.
Same goes for the the carts, the packaging is excellent and the carts feel solid.
Regarding the carts the console takes two at a time and they cam be hot swapped so no need to turn console off each time.
This is excellent. All the games are fully licenced so play really well.
All in all a great package and for £89 for the starter pack or £109 for the premium pack you can't go wrong to be honest.
