So I was playing Attack From Mars in Pinball Arcade just a little while ago, trying to clear the last wizard goal I needed by collecting the 1,000,000,000 Hurry Up Bonus (which I finally got!), but afterwards when going for Martian Multiball I was down to just one Martian left, the one right by the scoop, and I ended up hitting the scoop, to which the Martian laughs and shouts "MISSED ME!" XD
That actually really made me laugh 'cause being a video game programmer/designer myself I was thinking in the back of my mind, "Someone realized that exact circumstance could happen and someone intentionally programmed the game to play a sound cue when it does!" There's even the "Dirty Pool" award in the same game if you trap a ball behind the force field and then knock that trapped ball up into the hole at the back.
Seriously, these little extra details buried deep in the code are really what separates the awesome games from the average games. You've got things like the Crossover Bonus in Taxi, "You Missed Everything" in Terminator 2, Black Knight 2000 laughing at you if you activate magnasave yet lose the ball anyways, Breakout and Poker in Star Trek TNG, Lyman's Lament in Monster Bash...
These kinds of things intrigue me and because I'm still fairly new to real pinball and still mostly confined to playing emulated tables on the computer save for monthly league nights, I'm curious what other extra little details are hiding away in all the other pinball tables out there and if anyone wants to share their thoughts on them or details about the first time they discovered something on their own without knowing about it ahead of time! ; )
