The 3DS game still looks 10 times better than Resident Evil 2.
You're talking about 14 years worth of technology advancements since RE2's release on PS1 to the 3DS release.
The Playstation 1 had 2MB Ram and 1MB V-Ram!
The 3DS has 128MB which might seem paltry but is still 64x times as much.
It's not the same. It would look horrendous on modern screens.
Yeah but the newer game has a FAR more advanced engine even on the 3DS. Updating backgrounds from what are likely to be high quality renders wouldn't take that long, neither would the updated character models. Theres rumours that its already been done and it'll be released in september this year too!
