Killer Bunnies (and the Quest for the Magic Carrot) is definitely a different kind of game. It's not all that simple, but if you thoroughly read the guidebook and then play a few rounds through you can easily get the hang of it. My only anxiety with it is having to try and properly explain it to friends when I want to introduce someone else to the game!
It would be too complicated to try and explain the full premise, but it's a creative, fun, interesting, and unique game. There is enough variety and enough options for gameplay that each round is guaranteed to always be different. This is definitely not the kind of game that you'll get bored playing!
You can play the game with a minimum of two, although it's much more fun with a larger group. There'll be bunny attacks, chances to show mercy (or not!) to other players, funny card descriptions, dangerous weapons, and a whole lot of fun.
The blue starter deck isn't super expensive, and as mentioned before, there are a lot of booster packs you can add to the game over time once you get to know everything included in this deck.
So if you're tired of the same old board and card games you've played since childhood, Killer Bunnies is DEFINITELY worth a try!
