• StarCraft map: A continuous and dynamic with a rich and diverse information and actions.
• Minecraft world: A continuous and interactive with a procedurally generated and modifiable terrain and objects.

However, game environments also pose many challenges, such as:

• Representation: How to encode and decode the game state and action spaces in a suitable and efficient way?
• Simulation: How to create and run realistic and accurate game simulations and scenarios?
• Evaluation: How to measure and compare the performance and behavior of the AI game playing agents in different game environments and tasks?
• Adaptation: How to adjust and optimize the AI game playing agents to different game environments and conditions?

Game benchmarks

Benchmarks are the standards and criteria for testing and evaluating the AI game playing agents. it can include various aspects, such as game genres, game tasks, game metrics, game datasets, game platforms, and so on. Some examples of game benchmarks are:

• Arcade Learning Environment: A game benchmark that uses 57 Atari 2600 games as the testbed for general AI game playing agents.
• General Video Game AI: A game benchmark that uses a framework for generating and playing various 2D arcade games as the testbed for general AI game playing agents.
• General Game Playing: A game benchmark that uses a logic-based language for describing and playing various board games as the testbed for general AI game playing agents.
• AIIDE StarCraft AI Competition: A game benchmark that uses StarCraft, a real-time strategy game, as the testbed for specific AI game playing agents.
• International Planning Competition: A game benchmark that uses various planning domains and problems as the testbed for specific AI game playing agents.
