How are we classifying this, just dead live service games? Because if so I can give you
- Anthem
- Marvel's Avengers
- Babylon's Fall
- The Crew
- Evolve
- X Defiant
- Lawbreakers
- Multiversus
- Gundam Evolution
- Battleborn
These are still technically playable but may as well be dead
- Redfall
- Bleeding Edge
- Suicide Squad
- Foamstars
This is not an exhaustive list, just what I could think of off the top of my head. I'm sure I'll think of half a dozen more as soon as I post this.
I think to be a concord-like, it needs a few more specific things:
1: It
must be a game which the corporation(s) behind it believe is likely to be a smash hit, and give it a high position in marketing as a result.
2: Despite (1), it is immediately panned or written off at the moment of it's announcement by the larger audience, and flops immediately on release.
3: Ideally, it is a game that is online or some sort of live service offering. Something that will
only be playable long term if it gets mass appeal.
4: The reason for flopping is the game obviously being made by a group that's out of touch with the wider gaming market, ideally due to being some combination of:
-4a: Being behind market trends, such as a late arrival to it's genre, when said genre is falling out of favor.
-4b: Seeming to be self-evidently derivative of previous offerings it will compete with.
-4c: Having an outdated cultural outlook, particularly tropes associated with negative aspects of early 2020's pop culture (millenial humour, deliberate uglification, virtue signalling taken to obnoxious or overtly hypocritical levels, manchildren stuff).
I'd say the dichotomy between 1 and 2 is the most important. Some suits have to absolutely believe they're working with pure gold, only for it to get shot down in flames the moment the public sees it on release, for it to be a concordlike disaster.
With that rubric, things like Hyenas, Suicide Squad Kill the Justice League, and Foamstars are the obvious candidates, and historical candidates would be things like Diablo Mobile.
