What titles do you guys know of that always seem to have the same exact part, or parts missing from pretty much every one, and what part is it ?? A coworker and I were randomly talking about it for some reason. Topper's don't count because they aren't really "needed".
What I've seen.......
Street Fighter II - the plastic car inside of the playfield
Cue Ball Wizard - the pool stick
TMNT - the sewer lid
High Speed - Traffic light
