I don't think anyone will hate you, you clearly haven't even played the game so it's pointless to argue with you.
No because after I read that your the only man alive, I decided that it wasnt even worth trying because that 1 line tells me all I need to know.
1. I didnt know it was a harem game until I clicked on it and seen the tag.
2. Even tho im not a fan of harem I still would have given it a try if it had a decent storyline but because of the afore-mentioned reason I can tell it doesn't.
3. I know this type of game is not for me because im not so insecure that I have to have every women in the world and not have to have conflict or competition with another male character.
4. Games should have some type of male antagonist so winning/earning the girls is an actual accomplishment. Instead of having no real obstacles at getting the girl otherwise it doesnt really qualify as a game in my eyes. Its just porn with some pointless mechanics.
So no need to argue. Those and many other reasons tell me its not worth it. But you go ahead and have fun. Me no thanks.
