I am looking for a simple card game that would be fun for the elderly and at the same time would break the monotony of traditional card games, that they are currently playing. Preferably something internationally popular so it is easy to buy in the EU.
Edit: Thanks everyone. I bought The Crew and noted a lot of other games. Hope it will go well :)
Exploding Kittens is always a winner when I break it out.
I would also echo the Crew is great, especially for people that are familiar with traditional card games.
