Sonys entire GAAS future is really dependent on Factions being good out the gate.
So make the moves people were saying to make even, in 2013 before The Division was out. In random order
- Split from main game, launch as standalone game like Infamous First Light. Later, add to PS+ monthly game. Later, add to FP2 and "Instant Game Collection" / later, "PS+ Collection".
No need to kill the MP for the next single player game sales, or leave it out of a Remaster/Remake collection, it just exists as it's own deal.
- More weapons, skins, taunts, skills, temp perk boosters, more modes of vs/play, custom game lobbies to party leaders can quickly define custom play parameters ('shivs only', 'no throwables', 'no purchsable weapons'), more levels (there's areas in main game and the Left Behind DLC not in the MP. Later as more TLOU games get released, shove their maps into TLOU:F too).
- We want the same 4v4 team-based strategtic matches like we have, either Supply Raid, Survivor (1 death per round Battle Royal style), or Interroation mode, but we want infected roaming the map causing issues for both sides. PvPvInfected. Sort of like I saw the brief gameplay of Scavengers.
Back in 2013: Oh hey look, that new Left Behind DLC on PS3 actually has a scene where enemy AI fights infected AI! That wasn't too great, but you'd have to tweak infected AI and their resistance to molotovs for MP mode vs 2x groups of 4v4 anyway. But that'll come soon, can't be that hard, right guys?
- You can also keep adding vs modes with different gameplay objectives or parameters. Like L4D2 Mutations, but don't take them away as timed events, just keep fleshing-out the modes of play. We're not going to say no, so long as the original three also stay in-tact.
I can't believe it's not happened yet... Mark my words, some game will come along and split the gameplay/feel somewhere perfectly right between TLOU x Division, weather it's "Battle Royale" or some online world instead, and it won't neccesarilly be ND's slow asses. Too preoccupied with Remakes, Definitive Vers of 2, former TLOU Film that became TV Show etc.
Once that hits, it's hard to become 2nd, 3rd place, let alone most games just fail-out of the space entirely. People who want to play COD play COD, not RE4-6 which is RE trying to be COD, like so many games these days try to be Fortnite. Fortnite fans play Fortnite, shocker!
Edit:
For my money... if The Day Before isn't vaporware, it looks like a cool Division-style overworld, and it's easy to imagine going to the Supply Raid area in the overworld and run that "mission", or custom matchmake for private MP lobbies. As if it's in-universe day's event, rather than just an online MP match. The same way you're in Division's city, and you walk to the hospital for the hospital mission level.
But that kind of crap doesn't take 9 YEARS to develop/concept, when you have the building blocks yourself before anyone else (hello, Gaikai), and then had Division as a further proof of concept in like 2015 as well. Or whenever DayZ/PUBG launched.
