Yeah, there's no need. I only think it's be more worthy remaking RE2/3 instead of Gaiden, or make a new story featuring a mission with Barry and Becca.
All of us would like to see the original games remade, i already seen people wanting a newer remake of the first, but it woudn't be economically good for Capcom, so they wouldn't do that. You're right, they can't remake everything and be rmaking all the time, it's time to get some new characters and make a whole new storyline.
It'd bee nice to play as a spy who is infiltrating an Umbrella (or something like that) facility, so yoou fight humans, but they also release B.O.W.'s to stop him/her. I think the only human enemies in RE were thos cleaners in survivor.
