I dont really understand why it would be hard for them to do, they already proved that they can do it with revelations 2. All they have to do is do it like the remake make it pretty much the same as resident evil 2 on ps1 just make it look like todays standards, add a few new areas like the remake, no over the shoulder gameplay, ALYSON COURT AS CLAIRE CAPCOM!! They could also add in 3 and maybe do it as one game.... play as jill right up till she gets infected and then play as leon as claire and then back to jill again. Can you imagine how well that would sell if it was done right.
It's not that it WOULD be that hard for them. It's that it COULD be that hard for them.
1. It's more expensive than RE0 and REmake.
2. Since it's more expensive, it's a larger risk.
3. They have to balance fan demands with what is ACTUALLY feasible and find a way to try and **** as little people off as possible.
4. RE2 is often considered the best game in the series, and it could cause some backlash if not done to fans specifications.
5. Every single little detail has to be redone. You can't use the same engine as the original. You can't use the same audio. Granted, all of this goes back to the financial aspect of point one, but it costs THOUSANDS in simply voice acting alone...Let alone music composition, detailing the environments, updating the engine to run smoothly on modern tech.
There is so much more when building a game from the ground up than there is when just touching up older games...
