If you were a french kid in the late 90s/early 2000s and your parents didn't want you playing violent games on the family computer, chances are they would get you something from the “Uncle Ernest” series - or rather "Uncle Albert", as it was known internationally.
While those largely played like standard “point and click” games meant to have children hone their wits (you explore locations, fill your inventory with items, and try to find a way to use them to advance the story), they stood out by their presentation, being set inside an old travel diary which Albert had somehow magically filled with live animals and complex machinery. This gave the series a unique visual charm, and a cool retro aesthetic which borrowed heavily from Jules Verne and franco-belgian comics.
Overall, while those are in all likelihood not the masterpieces I remember them to be, they were probably decent adventure-puzzle romps with a cool atmosphere, and would be a good addition to the GOG catalog alongside similar games like the Amerzone or Syberia series.
