My personal favs are the Ratling pair

Jr and I have watched the Warhammer+ episodes of Cursed City and Blackstone Fortress. Cursed City looked great fun and Jr really enjoyed it. I then bought Blackstone Fortress and we watched the WH+ episode but neither of us enjoyed it - I just think it didn't translate to TV. We have yet to attempt a go at the game (I've assembled the minis but not painted them). I do love a boxed game.

My son has no interest in the hobby side of things, but will play as the enemies on both Blackstone Fortress and Cursed City. Another viable option are the even smaller boxed games like Space Marine Adventures Rise of the Orks, or Doomsday Countdown for 40k and WH: Lost Relics and WAoS: Crypt Hunters. These smaller game
