Was thinking about the different ways games communicate information to players, and how most games rely on inserts or backbox displays. It's pretty rare to actually put more discrete information right into the playfield itself.
Not sure what was the first, the earliest that's coming to mind for me is Medusa:
Was there one before that?
Scott used a similar idea in TNA:
Not thinking of other segment displays at the moment, those are the obvious ones for me because I owned them both. There must be more though.
Then there's straight up LCDs in the playfield.
Obviously Alien comes to my mind (and Full Throttle):
but the first time I remember seeing the idea done in this kind of way was Captain Nemo:
Can anyone think of more examples? It seems less common that you'd think.
