Bears no outward connection to the series they belong to because the series name was changed or removed altogether.
Alternate name: Series name change
The first video game about Series name drop was released on December 1995.
Reasons for this can be numerous, the most sensible being that the game begins a new sub-series that doesn't have much to do with the original(s) or the series is taking a new direction. Or the subsequent games are published by another who does not have the rights to the original series name and is forced to change it due to legal reasons.
