I can find some post‐’50s terms included in Fallout 1. If we accept the rule that the game must be written from a 1950s perspective, then this is clearly problematic. Some examples include:
- download
- downplay
- gigabyte
- scam
- sicko
- scumbag (pejorative sense)
- shithead
- suck (slang sense)
- wuss
- yucky
And this is by no means exhaustive.
