I'm trying to rationalise it because the companies investing in upgrading the visuals have to.
You ned a good argument. You made a game, sold n thousand to current gamers. Lots and lots of gamers didn't buy it. Is it worth improving the visuals to try and sell it again to those gamers that didn't buy it, or just let it run on the emulator and sell it cheap in the store?
Perhaps a means of encouraging patches would be to make a "PS5 Enhanced" tag have some perceived value. That's easier said than done, of course, but the relative dearth of content at launch might aid the matter.
If a hobbyist can do it in their spare time in, I think, a matter of months (I'll go check after this post - I've not finished watching the whole Digital Foundry video yet,) then it's reasonable to extrapolate that a handful of professional programmers being paid full time ought to be able to crank out patches at a fair pace.
According to
this, the average entry level video game programming salary is $44,000. Even though 1 hobbyist can do it in a few months, I'll be conservative and say 2 programmers for 6 months = $44,000.
Is $88,000 a reasonable investment? I'm not an investor, but that doesn't look to me like too much money to have a punt at a profit.
I suppose the next biggest cost would be QA. Perhaps this is something that Sony could handle directly or be involved with, lending resources? It would be an expense for Sony, but it would also be a means of gathering large amounts of data from developers who are looking to generate a profit anyway.
Each investment runs a chance of breaking even or even generating a profit. All the while, and also when they fail to break even, Sony gather more data relating to BC. Microsoft are definitely ahead on this matter, as it's been part of their DNA for decades, and Sony shouldn't risk getting left behind.
Personally I'd love a "PS5 Enhanced" label on games from the PS1, PS2, PSP, PS3, PSVita, PS4, and PSVR:
- 4K60 (or 4K120 in PSVR's case)
- cloud saves
- screenshots and video recording
- custom background music
- social stuff like party chat
That's it. If they didn't have trophies (e.g. PS1) don't fart around with the expense of putting them in. Keep it cheap. Get it running at 4K60 and take care of the legalities that would allow for all of the system-level features to operate.
