FC i think is a game that caters n indulge player's power fantasy... while this game's concept seems to be the exact opposite (i'm a bit alarmed by phase 1 plan to be grind monotonous phase as slave, that doesn't sound like it's gonna leave a good first impression)
The catharsis from the rise of power has to be really satisfying if you want players to forgive being subjected to those early grinds
But, if the game is intended to reach other niches (not the typical FC fans, those who want to play as slave), then ignore my comments lol
