Undertale

Undertale is a groundbreaking indie RPG from Toby Fox that subverts traditional genre conventions. Players encounter monsters but can choose to fight or find non-violent solutions through dialogue and mini-games. The game remembers every choice, leading to multiple endings that are drastically affected by the player's actions. Its bullet-hell style combat, memorable characters, clever writing, and iconic soundtrack created a massive cultural phenomenon.

It ranks for its profound emotional impact, innovative mechanics that tie gameplay to narrative, and its powerful message about empathy and consequence. It offers exceptional value as a lower-priced indie title with high replayability to experience its different routes.
