- Most Factorio players are post-college age, so they don't have to worry about parents making them stop playing Factorio due to a somewhat bad word, but I have seen mention of Factorio players who are teenagers, and Factorio players who let their children play.
- Factorio has fairly little text, and "bastard" is the only word that is bad whatsoever.
- The way it is used does not really insult anyone other than the player.
- Most people don't see the achievements list until after they buy the game, so it probably won't influence their buying decision.
- Most Factorio players probably don't care that it is a bad word, but some might.
- Long-time Factorio players have probably gotten used to or even attached to the name, but new players would never know.
- Factorio has exceptionally little gory violence and bad words compared to lots of other games. Does that mean it has an excuse to use one or should keep from using it?
