but it's not a process you can repeat. sony would be able to pull it off once, maybe 2-3 times if they exploit their walled in console demographic.
I disagree.
Let's take TLoU as an example. The mainline game comes out, then knowing there's a 5 year turnaround on the sequel (because reasons, hur dur long time to make games), in between that you offer TLoU online multiplayer.
It's a game knocked together in a month (GoW1 MP was made in a month...) and people have 3 maps to play. It gets big figures for 3 weeks then starts to drop off. To keep people interested, more levels are made, a new gun, a new character or skin. Rinse and repeat.
Sony wouldn't need 4 version of TLoU online, it just needs 1. Do the same with each franchise; GOW could be a fighting game, Horizon could be a Monster Hunter rip-off. Use the assets in the game that already exist, stitch together a multi-player, or at the worst, a co-op experience and sell bits of levels and skin on a regular basis.
Bonus: The online game can strip away any wokeness or fag-messaging because there's no story, just death and victors.
This worked so well for WoW and GTA that the devs gave up making other games, which was a retarded idea. Keep the cadence of releases, the flag-ship titles, preferably single-player only to not burn-out the online and to reduce cost.
That's going to keep interest in a franchise, while making profit, more than 1 game every 5 years. And oh, the game is chock full of pervasive and invasive DLC, MTX and P2W options.
