The battle system ATB has to remain true to the original. So does the materia and the levelling up system. Let's not forget that the game mechanics are based on AD&D/D20 and other dice rolling RPGs it shouldnt be over complicated or over simplified. In other words just like the original. Updated fmv's possibly 3d are OK in my book as well as more rounded polished sprites and NPCs .If S,E change any the core game mechanics and feel of the game (that statement does not include resurrection of Aerith, please bring her back or at least axe Cait Sith) the game will flop with the original fans And only be a hit in the eyes of modern players I.e the fps generation. Chrono trigger was an extremely well polished game in both playability and longevity but I still take secret of mana over it as well as ffvi, ffv, ffviii and ocarina of time. I did like the time travel element of CT though especially the way you could change things in one time and change the future.
