When I see the same thread about Sony blowing up super fast on Era/GAF/Reddit, I know right away something fishy is going on. You can't take anything at face value these days.
Anyway, I don't think there's any platform/store with nothing at all besides the item you want and that's it.
I'm on Eneba, I clicked on Fortnite and I get "Gamers also viewed" with other games and DLC.
Same on Fanatical: screenshots, videos, DLC, bundles, user reviews etc
Sony uses the "Official News" section for basic stuff like updates, DLC or patch notes.
Example for Resident Evil 4: Gold Edition announcement, Free VR mode out now, Separate Ways launch.
Rebirth: Accolades Trailer, Launch trailer
Horizon: Lego Horizon Adventures, Zero Dawn Remastered, community spotlight etc.
I actually think it's useful most of the time. Is it really that bad?
Where are people shopping if this is an issue?
