According to ESRB, this game contains: Blood, Violence
Parents should know that, while monsters do bleed in Summoner: A Goddess Reborn, the blood is a relatively subtle effect. It drips when players hack at enemies, but there are no pools of gore like in Resident Evil or even Conker's Bad Fur Day. Nor is there much bad language: I counted two "damn"s the entire game. But the women warriors do wear form-fitting armor and one is a busty robot.
Female gamers will find plenty of strong women here. It's just that the game surrounding them leaves a lot to be desired.
Gamers who think most RPGs are too slow will like Summoner: A Goddess Reborn's hack-and-slash battle system, but little else.
Newcomers to the Summoner series should have no problems following the game's plot; this is the first title in the series I've played and its story seemed self-contained to me.
Deaf and Hard of Hearing gamers can turn on captions for the cutscenes, and won't get tripped up by significant auditory cues.
