an absolute dream of mine would be for the Nemesis REmake to be part of RE2. They could even release it under the subtitle Escape Raccoon City or Raccoon City Collection just like they did with the 0 and REmake remasters/Origins Collection. I wouldn't even mind if they made it DLC to RE2 since it was technically a spin-off of that game and does use some of the same assets.
That would be great indeed, but looking at the way games are made these days, and how many companies seem to value graphics over content, I'm afraid it would lead to at least one of the entries, if not both, ending up considerably shorter than the original. Didn't the RE3 portion of the Chronicles end at the police station? Granted, that was an entirely different story, but still... I doubt that Capcom could pull off a combination of these two awesome games in a way that would satisfy us.
