More characters are always good.
These feel more beginner friendly - so advanced and non-completionist collectors could probably skip.
Marc is probably my favorite boss for solo play though - so YMMV :)
I love how you create your character, with choices based on personality and not just "that card is op". And the story tidbits are great. Like I heard in a review, this game does not penalize you for exploring and taking your time. Loving it
Really cool pack and cheap to add a stack of encounters your game. Be warned some of them are pretty wild and very different from those in the base game (a lot more extreme benefits). I wouldn't add them in early games but nice to spice it up later on. Just make sure everyone knows the encounter deck has been boosted as it will influence play
