but isn't the map the only thing lifted from metroid? i mean, the free roaming, inventory, equippable weapons/items, leveling up, money system were all done in cv2 and that's what sotn followed.
i prefer to call it metrovania. because it's not metroid.
also on topic, the quality of the games is slowly declining. sure, they sugarcoat the games with pretty colors and stuff, but the sprite work is slowly degenerating after taking a brief jump in aos, the storylines are getting worse with each title, not to mention the protagonists too.
not mentioning ooe at all, because it's not out yet so until it is i'll treat it as it doesn't exist. once it's out and i play it through, then i'll probably change my mind.
until then though pork is the last game, and its quality took a big drop from dos, aos, even hod.
