This game is a typical Eric Eve game:
Good points of Eve games: several NPC's, large map that doesn't really need mapping, optional side quests, great writing, interesting plot.
This game is a bit like Dante's inferno, but with a more 'modern' take. In particular, there are forces that disbelieve the truth of heaven and hell, and the game doesn't say who's right and who is wrong. As a case in point, one of the first things you see is that hell is closed, due to mythologicalization.
The general gameplay was very enjoyable. It felt like Blue Chairs without the drugs and profanity.
Bad points: trophy-ization of women.
Just like Elysium Enigma with the naked Lena and Blighted Isle with Betty the buxom, All Hope Abandon is chauvinistic. The main woman is referred to frequently as just 'the blonde', and there is a green-skinned demon, who makes you uneasy because they 'use sexuality as a weapon, just like many mortal women'.
It's a shame that these games all pigeonhole women, as otherwise I would strongly recommend them to everyone.
