We just got this question about the game Chupacabra: Survive the Night. The obvious tag for the game (chupacabra-survive-the-night) is just a bit too long (28 characters). Should we just remove the "the" (chupacabra-survive-night), or shorten the whole subtitle (chupacabra-stn), or remove the subtitle entirely (chupacabra) or something else? Do we even have a standard for this?
Until and unless we discover a specific need to distinguish Chupacabra: Survive the Night from some other game named "Chupacabra", I'd say we should just drop the subtitle and call it chupacabra. That's the simplest and most obvious solution, and seems to work fine here.
If we do find ourselves needing to disambiguate the tag (as has happened with the star-trek tag on scifi.SE, for example), something like chupacabra-stn could work. But if no such need exists, there's little point in making the tag longer than it needs to be.
