Strongly dislike, but might tolerate if the rest of the game is good enough:
- Permadeath.
- Randomized procedural content.
- No single player mode, only multiplayer.
- Online leaderboards.
- Games with no win condition, just a high score.
- Games that brag about how difficult they are.
- Microtransactions.
- In-game ads.
- Intentionally ugly art style.
- Quick-time events.
- Luck-based missions.
Dealbreakers, will never knowingly play:
- Microtransactions that are necessary for completing the game.
- Any use of cryptocurrency/blockchain tech.
- Any use of generative AI.
