Keeping this in view, what does single game mean?
A single-player game is usually a game that can only be played by one person, while "single-player mode" is usually a game mode designed to be played by a single player, though the game also contains multi-player modes.
Also, are single player games dying? Single-player games are not dying. People have been eulogizing single-player games for over a decade now, but 2017 was a pretty good rebuke to the notion. AAA publishers turned out amazing single-player hits like Horizon: Zero Dawn and Resident Evil 7.
Similarly one may ask, what are single player games called?
A single player playing against a set challenge is now commonly referred to as single-player mode or "campaign mode" (amongst other terms; e.g. "story mode").
What is an AA game?
A Double A game (AA) is a game that fail to reach the milestone previously set by AAA games. They generally have a lower budget than AAA games. The A/B games are those poor games that had a great idea, but the development team just couldn't make everything work seamlessly together.
