While related to an early discussion on retro gaming, this isn't the same.
I noticed a question got retagged to old-games, which investigation led me to see that it has a 66 questions (excluding two closed game-rec). 26 of them are not identify-this-game, making 40 of them exceptionally redundant - the majority of identification questions are about old games, otherwise you probably didn't forget it.
We lack a consistency in the application of this tag. There's also no real definition for what constitutes "old" games that we can use to build any consistency. There is a danger associated with certain age definitions, the same which makes upcoming-games a particularly dangerous tag: tags that change over time cause a lot of problems.
We could use a definition to the purpose of this tag. To me, the tag mostly conflicts with the usage of platform tags. One knows that an NES game is old by virtue of it being on the NES, and anything modern-made for an old platform probably stands out more by its own name than by the fact it lacks an old-games tag. Its primary usage that makes sense to me is for generic questions about older games that can be asked without any particular platform being of concern. In that case, there are a lot of questions with it that should have it removed.
What does everyone else think? What does old-games give us?
