The sewer levels in Crash bandicoot 2 weren't bad or annoying. Also Sewer Speedway from Crash Team racing was a fun racetrack.hittite said:Any sewer level. Seriously, name one that didn't suck.
Although sewer missions that were bad were the ones in Jak games such as Jak 2 and 3, also the sewer racetracks in Jak X were very bad. Those were annoying. Also there's a sewer mission in Call of duty: Finest Hour that gave me permanent nightmares.
