Make your perfect Final Fantasy (from setting, to music to battle system)

[Scoobes]

Setting - Cyber-punk future/sci-fi setting, with at least one giant disaster leading to at least 1 continent becomming a post-apocalypse landscape. I think having to deal with the survivors could be quite cool and shocking. Oh... and proper towns.

Music Composer - Uematsu

Characters - 8 playable total, 4 male, 4 female.
Male:
Main= Early 20s
1 Immortal character, mysterious, been alive for a long time (effectively a divine being, but with a dark past)
1 Father on the run from the law for a crime he didn't commit
1 Cid... gotta have a Cid

Female:
1 Love interest (gotta have at least 1 of these), 20s
1 late teens girl whose parents have been killed after unwittingly helping the bad guys
1 Scholar, intelligent, mid 30s
1 divine being with no knowledge of her ancestry

Bad guy: An immortal being.

Genral plot outline - A revenge story is always good:
1. Main bad guy and main good guy are friends, yay... then a betryal event, boo!
2. Bad guy attempts to gain the powers of a old and evil god, but is being manipulated by said evil god's son (let's say this is the reason for betrayal earlier). Evil god possess main bad guy. 3. However, this frees up a bunch of other old gods who pass on there powers to our group of heroes, woop dee doo...
4. Evil god starts a conquests that lays waste to at least 1 continent. Creates demonic creatures as his army and finds ways of forcing common people to obey his will.
5. Heroes traverse wasteland with there new powers and fight old god, kill him, everyone's happy... except for the continents that's now a wasteland. Cue Fallout style sequel :P.

Battle system - Like Grandia. Spells acheived through technology upgrades (kinda like nano augs in Deus Ex, have a set number of slots that increases through level up and 1-off items) instead of divine powers. Gods enable summonings and extra abilities/enhancements and can assign a god to a character like FFVI. Multiple weapons; single slot. Single slot for armour. Multiple slots for accessory's, increased during lvl up.

Length - 50 hrs main quest; 200 hrs with everything
