People love to shout about a game being dead or dying. Recently its been Battleborn getting such cries, over and over again. Why do they think its dead?
Because very few people are playing it.
But here is the thing. A Game is not dead until its no longer playable. Games do not just vanish. Can you play the game? Then guess what, its not freaking dead. Are the official servers still active and maintained? Then its not dead!
It might be unpopular sure, it might have a very low playerbase, but its not dead.
Battleborn in fact is slowly getting an upswing with the current 2k Humble Bundle, as you can get the game at the $15 tier along wtih a ton of other good games.
You wanna know what a dead game looks like? Star Wars Galaxies. Warhammer Online. Planetside 1. Darkspore. These are games that literally cannot be played (officially at least) any longer. They are gone. Vanished.
People think a game I have recently got back into playing, Warmachine Tactics, as being dead. But the devs are STILL making new units for it, and content. People STILL play it, the forums are STILL active, and hell I am planning a few PVP Matches this weekend. Its not dead. It just has a small but dedicated fanbase. Hell, if you are curious about WMT, might I suggest checking out the Demo the Steam Page offers? Its a good turn based strategy game, and the Demo even lets you play PVP matches!
When a game is no longer supported and officially playable, then you can call the thing dead.
