Mario, eat your heart out, there's a new hero plumber in town. DrainSim is an upcoming indie game that involves saving a city from flooding, and it looks a lot more exciting than it might sound.
The closest Mario got to actually doing some plumbing was fixing pipes in Beanbean Castle in Mario & Luigi: Superstar Saga. Perhaps Nintendo thought unblocking drains wouldn't make for great gameplay, but then it didn't have today's realistic water physics on hand for the original games.
