I'm designing a card game based on an ancient fairy tale book. So far my game consists of some hero or character cards with 3 attribute: coins, strength and intelligence. And there are quest cards with the same 3 attributes and what you do is to pick character cards and when you reach to a quest card level, make it complete and then you do that card's actions.
My game at this time is basically a hand management game and somewhat similar to games like splendor and "Quests of Valeria".
But what if I want to add a taste of adventure games to the game with heroes, quests, items, treasures and so on? I still insist on it being a card game without a board.
How can I make my game a little bit more adventur"ish"?
