Review Detail of GatchaJoe in HP: The Magical Gamer

So we start off with Harry Potter in an AU version of the HP verse i've never seen before. Mom is alive, but dad is dead (so Harry can add his mom to his harem later). He also has a very close sister (also so she can be added to his harem later). He gets the gamer system, that almost right away starts giving out really op rewards, and Harry also almost right away becomes extremly arrogant. Harry then goes on a murder spree of thousands of criminals to level up, becoming even higher level then Dumbuldor and Valdamort before even starting Hogwarts. Harry then attends Hogwarts, showing off, he the best, popular with girls (basically every girl he meets with end up in Harem), ect. O and then his sister gets killed for basically no reason exept to give the 11 year old motivation to leave and exsplore the multiverse or whatever. All in all, not very good, and I've decided to drop it.
