So...are we thinking a Rogue Like dungeon crawler with Final Fantasy jobs/lore? I mean it has potential if done right. I don't think it would be for me but I could see it being liked by many people.
Have classes with special abilities, random lay-outs per death and you start over but some aspects can carry over, maybe accumulated Gil can be spent from the last run to purchase boosts and/or passives for all subsequent runs but any unused Gil gets tossed away so it's "Use it or lose it".
I can see it being a decent spin off. Doubt it can ever be a main liner.
