[2023] Teamfight Tactics Match History

You're pretty close here. The wording we're using is we want to discourage third-party applications from reducing the diversity of the game, providing competitive advantages for players, and playing for the player.

Showing the rules of the game are fine. We did discuss highlighting champs in the shop and decided it might provide an advantage for players re-rolling quickly. I believe the TFT team was looking at doing something to highlight this as part of the game anyway so that every player had equal access to this (but don't quote me on that). We encourage developers to start a discussion with us as early as possible so we can give feedback on ideas.

As for the last section, you're spot on. Apps that play the game for the player are definitely things we like developers to steer clear of. They basically remove skill challenges and create less diverse games.

Overwolf overlays aren't problematic in and of itself. What the overlay is does might be. This means one overlay might be fine while another isn't. In the article, we discuss the things we'd like developers to think about and avoid doing when making apps. Apps that display the rules of the game are fine. Offering general suggestions are fine. Offering suggestions based on in-game context is generally off limits, but if you have ideas that don't create a competitive advantage feel free to have a chat with us.

My team mostly focuses on communicating with developers whose goal is to design apps that are inline with Riot's policies and contribute to a positive player experience. For those developers, we're outlining what those policies are and the areas where we believe the player experience can be improved. We offer guidelines to help guide developers toward healthy areas of development.

There's another team that handles the development of tools meant to break games and degrade the player experience; they're anti-cheat. You'll see them talk about their work from time to time, but the more they talk about their methods the easier it becomes to circumvent those methods.

Our first step is always to reach out to the developer and start a discussion. This article is so we don't have to do that for developers already in the ecosystem. But you're right if there's a developer whose intentions are good we'd work with them to ensure their product aligns with our policies.
