What would you consider Metal Gear Solid The Twin Snakes or Resident Evil for Gamecube? It's not like Wind Waker that tosses in a few new things and fixes a few issues. It's a rebuild from the ground up but still familiar territory for people that have played the original.

I'd say both are remakes. The Twin Snakes, however familiar, features new voice recording, a rewritten musical score, graphical improvements, new cutscenes, and new gameplay features originally introduced in MGS2.

Resident Evil features new graphics and sound, new rooms and areas, re-recorded voice acting, new gameplay, and new plot points.
