Sweet Home ~H na Oneesan wa Suki Desu ka?~ : A question regarding the two games.

[LonerPrime]

Hello,
I recently got around to downloading the Sweet Home series but I am stuck at a crossroad where I am constantly kicking myself for not being better at reading Japanese.

You see, there are 2 releases:

Original
Latest

Now I happen to have both and I am quite confused. As far as I can tell, both are quite identical with the difference of animations and new storyline in the Latest one. But my question is, is there anything at all in the Original that is missing from the Latest? The reason I ask is if there isn't then I would like to delete my original copy so I can free up some Hard Disk space. So any guidance/opinions regarding the matter are quite welcome.

Regards,
