Both games were released around the same time and were pretty similar. Both are great games, but which one did you like better?
REmake. The rehash of an original was brilliant, and I think 0 had some flaws. For me, the lacking of boxes in 0 was irritating, having to drop an item and come back to that exact same spot if you wanted it back (I know Real Survival incorporates this, but it's not forced to play Real Survival).
The Partner Zapping was cool, as were the locations, but REmake I think edges it in every department for me. Characters and character development, locations, atmosphere. Though 0 is still a very good game.
