I do a lot of Roleplaying and need some games for in-between and “gambling” for the others I play with. I don’t want my players to learn a long and massive game. Something that feels a bit medieval and uses dice of 55/32 card decks would be perfect. Like Gwent or Zombie dice. Maybe where you can cheat?
For in between, you could try the Wrath of Lich King board game. Pretty simple rules with good variety of heroes.
Five Minutes Dungeon is also cool. Each session is literally 5 minutes.
