When i read the tweet and saw some of the hints towards LOD i wondered how you would react XD, not to mention they had already teased us about it some months ago.
That being said... ahh... i honestly dont think its gonna be LOD its not that i hope that its something else, in fact i would take a LOD remake over a Remake of DeS or ZOE2 in an instant, however the reason i just cant believe its LOD is because if you have played that game you would know that remaking it would be a GIGANTIC task on parallel with remaking FF7 (a game so big it had to be broken into parts because there was no way they could fit all of that in one PS4 game).
Just think about some of the towns or kingdoms you visit on the game (like the one of King Albert), imagine making that town on PS4 and being able to explore ALL of it instead of a couple of streets like in the original, that would be just too much and thats not even talking about the whole map which is huge, in the original game you would just travel from place to place by moving Dart over a map, if we are talking about a remake of this game i expect that map to be an actual world you can explore with all the places (towns, cities, dungeons) on it, like The Witcher 3, GTA, or any other open world game.
Not to mention they said they are working on 2 games and i just dont see how its possible for them to be working on something so huge like LOD while also remaking another game at the same time.
However there is a chance they are just remaking all the assets and making it look like a brand new PS4 game without updating the technical aspect of the game, (like making it open world, making the cities and towns fully explorable etc), but if im honest i would be dissapointed if thats the case because i want this game to get the FF7 treatment, that being said i would still take this version of the remake over nothing and would still be incredibly hyped about it.
