What about bigger games like BG3? What’s stopping me from buying it full price, copying the files somewhere and then instantly reselling it? It would probably force them to implement strict DRM restrictions, and probably the nasty rootkit kind.
The same thing that's stopping you from downloading the files now. A combination of ethics and the value legitimately owning the game adds to your purchase.
Since getting a PS5, a good chunk of my time has been spent with my PS4 library I fell off of when loading was too obnoxious. I had a Last of Us Left Behind save on grounded difficulty that I had never beat because, while I enjoy the brutal difficulty of the last encounter, waiting to load every time I died was miserable. The much faster (but slower than PS5 games lol) load time got me over the hump.
I reluctantly pulled the trigger on PS+ with the Black Friday discount because I have to have it to play Madden, and downloaded Ratchet and Clank: Rift Apart because it's included. It does a beautiful job leveraging the PS5's features, and it's really fun. I also love the art style. Too many games go too hard at "realism" instead of just making a beautiful game.
Also, because I got it as a PS+ game years ago and just regained access without buying it, started playing COUNTER SPY again. I don't think it ever got the attention it deserved. It's a fun 2D stealth platformer smoothly combined with a cover shooter mechanic where you can aim and shoot in 3D from fixed cover points. Dying raises the threat level, and if you raise it past DEFCON 1, you get a countdown timer to complete the level or fail your mission. There are a couple mechanics to lower the threat level, and you can choose to gain your intel from US or russia themed enemies who are otherwise the same. Levels are procedural, and there's meta progression by unlocking guns. It doesn't really get to rogue lite because there aren't random powerups, weapons, skills, etc, but it feels similar otherwise. I would have loved a sequel expanding on the premise, but it's still worth a run every now and then.
The tech difference between the PS4 and PS5 is massive.
It genuinely can be a complete overhaul, more than just graphically. Also worth noting is that the $10 cost is just the difference in pricing from last gen, and doing split gen like that has let them keep the PS4 versions the same pricing without making them rebuy games when they get a new console. They just make up the difference.
I don't and won't buy a lot of full priced games because I can wait, but their approach really isn't that bad.
