Here's why:
* Alternative methods exist: You can use the Strength HM to move boulders that would normally require Rock Smash.
* Accessibility: There are no mandatory areas in Fire Red that are only accessible with Rock Smash.
However, Rock Smash is helpful for:
* Finding items: There are some hidden items behind rocks that can only be broken with Rock Smash.
* Catching Pokemon: Certain Pokémon can be found in areas accessible only after breaking rocks with Rock Smash.
* Optional areas: Some areas in Fire Red are accessible with Rock Smash, offering optional challenges and rewards.
In conclusion, while not mandatory, Rock Smash can be helpful for exploring hidden areas, finding items, and catching Pokémon. But you can complete the game without it.
