In a gateway boardgame (like Azul or Splendor) how many resources there could be without being overwhelming for the players? What else can I do to make it simple to learn?
The number of resources in a gateway board game should ideally be limited to no more than 5-6 different types. This helps to keep the game simple and easy to understand for new players. Having too many resources can make it overwhelming and confusing for players to keep track of, especially if they have different properties or interactions with each other.

In addition to limiting the number of resources, there are several other things you can do to make a gateway board game simple to learn:

1. Streamline the rules: Keep the rules simple and straightforward, and avoid adding unnecessary complexity. Try to make the rules easy to understand by using clear and concise language, and provide examples or illustrations to help players understand how to play.

2. Provide clear objectives: Make sure that players understand what they are trying to achieve in the game. Provide clear goals and objectives that are easy to understand, and make sure that players have a clear idea of how to win.

3. Use intuitive game mechanics: Use game mechanics that are easy to understand and intuitive. Avoid overly complex mechanics that require a lot of explanation, and focus on mechanics that are easy to pick up but offer depth and strategy.

4. Provide reference materials: Provide players with reference materials that they can refer to during the game, such as a summary of the rules, a reference sheet for the different resources or actions, or a quick-start guide to get players up to speed quickly.

5. Playtest and iterate: Playtest the game with a variety of players to see where they struggle and where they excel. Use this feedback to refine the rules and mechanics, and make adjustments to improve the game's flow and balance.

By following these tips, you can create a gateway board game that is simple to learn, but still offers depth and strategy for more experienced players.
