What is the difference between 'Top Critic Average' and 'OpenCritic Rating'?

The 'Top Critic Average' is the simple numeric mean of scores, while the 'OpenCritic Rating' (Tier) categorizes the game into levels like Mighty, Strong, Fair, or Weak based on its performance relative to other games.

Can I see reviews from a specific publication like IGN or GameSpot?

Yes! Use the `get_game_reviews` tool with the Game ID. The response will include a list of individual reviews, identifying the critic and their publication for each snippet.

How do I find the best games released in a specific year?

Use the `get_hall_of_fame` tool and provide the target year. Your agent will retrieve the highest-rated games for that period according to OpenCritic's aggregate scores.
