That is exactly what I don't want to see happen. I like Crisis Core just fine, but FF7 doesn't need a game play change that drastic. Tweaks are fine, but anything more and it will change the character of the game too much. At that point it might as well be FF7-2.
thats what it shoulda been man. a direct sequel opens them to switch up the gameplay as they please. new characters, story elements, etc. way more possibilities & freedom. a remake, while refreshing, is still restricting
but if ff7 remake is successful (and we all know it WILL be) then they can and will make a FF7-2 anyway
