Techno City/Large Factory cliché
From Sonic Retro
Jeez, Eggman's one busy little scientist! It always seems like he's building a technological city for himself in every game. I've also included levels that are set in factories of city-sized proportion, since they both seem to go along together. Metal galore, electric sparks, spikes, and nasty badniks are a few of the things often found in these zones.
