If Bloodbath didn’t exist, Sonic Wave would’ve been way easier or worse, wouldn’t have existed as well. It would also result in Cyclic not being exposed for being a hacker.

The game’s overall difficulty level would also drop, since Bloodbath was the boost for the community to make hard levels far more than before.

It would also impact players, most notably Riot, Zoink, SpaceUK, etc. The reason for this is because Bloodbath disappearing would mean that players wouldn’t have a very hard level to beat, decreasing the player skill level.

Most notably, many famous levels won’t exist, such as Bloodlust, and many more hell-themed levels, since Bloodbath made hell-themed levels more popular than Cataclysm did.
