With the game more than likely being ran at 4k, I expect to see the file size somewhere around the 7-10GB range. Not bad by any means by today's standards. I do find it funny that during the PS3 days I was angry that so many games had a 5GB install. lol
but those PS3 games had almost lifelike graphics and visuals! however a 16bit graphic game like this remake is just going to be upscaled to 4K yet the graphics may look almost exactly the same. as an expensive 1995 JVC brand CRT television back in the day.
We have improved our technology since then, and even
IF this this game was, like lets say 50mb that would still be awesome!. even though it would mean this new game only took about 10 times as much harddrive space as a SNES ROM on a PC.
point said, if modern games took less space, that would mean more games for you, and less dependency on external hard drives and buying an another same Generation console.
I mean if people could fit more modern games on a modern hard drive SONY Microsoft would more likely sell more games, off their digital store. because people could then fit millions of games on one of their console's hard drive
and there would not need to be so much more technology tossed into landfills or melted down, in which is actually an expensive process.
