I think Final Fantasy 7 and 10. the worlds were so well build. And in current times of terror, climate crisis, wars, so many topics were in the games.
As other games i mention Limbo, Ori and Hollow Knight. The have a really great athmosphere. Just thinking about these games, makes me remember of the feeling playing them.
And the biggest game in my list is Elden Ring. So many wow things in there. And the shear amount of content ... Just blew my mind.
That is easy to answer for me.
Mansion of madness
I have played so many rounds with so many different people. The game is complex enough that each round is different. But easy enough to geht people to start with. Easy to play hard to master.
The digital game master via APP is great. I had so many games in which the last player actions decided the game. After some hours of game time. Your actions feel so impactful.
