I seriously doubt Freedom Wars is gonna play much like Monster Hunter. I feel like the similarities end at fighting large enemies and working in groups online. It really seems like half the games called MonHun clones aren't even that similar.
It looks fantastic though, it really needs to come out here.\
It does fight big ass monsters, but there is one big differentiating factor: It supports 8 players (right?). Freedom Wars definitely will have different emphasis and there will be more than just taking down big monsters. Perhaps there will be PVP too if it support 8 players mode.
