My nightmare is having an FF7 remake with the same dull combat. But hey, everyone WANTS it to be the same just with pretty graphics hurr.
No I actually do want things changing, but not things that will ruin it. This is what I think can work (just my opinion here)
1. Battle system remains the same. However, enemies are unforgiving. if an enemy is weak against holy, you can exploit this enemy with alexander-elemental attack and make the battle far easier, otherwise its a lot more difficult. Enemies are harder with more HP and attack strength; unforgiving if you do not have the correct armours. Grinding is a tad easier. Sense materia becomes the most important materia because with it you find an enemies weakness and unlike the original you
do have to exploit it. Relentlessly attacking will only work with few enemies.
2. Gold saucer has updated games....around 10-20 more than we had originally, with a choice of "classic" old graphics for the originals. More areas in the gold saucer too other than wonder, chocobo etc. The chocobo races need a full overhaul also, away from the rather basicness that currently exists.
3. Graphics overhaul yes. But not adding ANY more cutscenes or visuals that were not there before (aside from Gold Saucer). Now I get flamed a lot for saying this but I am going to say it: Final Fantasy VII is a good story that does not often question your suspension of disbelief, the given world is pretty well managed (Apart from cait sith imho). This next point ties in with this and graphics: Under no circumstances should a remake attempt to hve out of control physics, like cloud flying at sephiroth defying gravity, as this weakens the impact of Sephiroth's strength. Under no circumstance should a remake make silly drawn out fights or scenes. When Sephiroth kills those 2 soldiers, or attacks tifa, that was DRAMATIC because it was 1 slash over. That is good. having him fight for 5 minutes like AC, weakens the dramatic tension.
4. Increased realism. By this I mean blood, and an emphsis on real suffering properly portrayed. For example, when sephiroth slashes those soliders in Niblheim, my way would be them screaming, blood, and neck slashed. We don't have to see the actual cut, so it remains a 15 or less, but the drama is much heightened by this.
5. More materia, possibly based on water, holy, wind that were much missed in the original aside from 1 summon for each.
6. New soundtrack should have black mages and orchestral and piano pieces to make up 1 alteranate soundtrack with the option to use the original music in the config.
7. Voice acting option to be disabled in config
8. 2D system kept (apart from battles and world map). I know most people want this to be full 3D but I don't.
9. Translation overhaul
10. Cait Sith removed and replaced with a Shinra Employee under Reeves orders (please nooo flaming me. I know some of you love that bouncing White git.)
Those are some off the top of my head....
