Since we are in !boardgames@feddit.de I will ask the question: How would you design Vampire Survivors: The Boardgame?

My take: The one thing I would definitely want to preserve is the massive power escalation, both for the player and the enemies. Perhaps a deckbuilder with upgradeable cards? Like the transform cards in some Ascension sets but more increments. Each turn you'd have to deal with a large number of enemy cards that are arranged in a grid around you. Your cards would give movement, attack and defense. You'd be solving a quick spatial puzzle each turn to get the most out of your hand.
