I like Mass Effect, Naruto (and Naruto crossovers), Ranma 1/2 (and Ranma 1/2 crossovers), Bubblegum Crisis, Xenosaga, Xenogears, Mortal Kombat, Fallout, Stargate, Star Wars, Halo (in crossovers only), Final Fantasy games, Bleach, Harry Potter, and a few others I can't recall right now.
Naruto x Any female (especially Hinata, Anko, a younger Tsunade, female Haku, Temari, and Uchiha Mikoto. I don't mine Sakura, as long the writer re-write her into a nicer girl towards Naruto or sees Sasuke as a rat and becomes nice to Naruto.) (Naruto)
Naruto x female harem (Naruto)
Naruto x any crossover female or harem (Naruto Crossovers)
Ranma x Kasumi (Ranma 1/2)
Ranma x Nabiki (a good Nabiki who does her things to help her family) (Ranma 1/2)
Ranko x Nabiki or Kasumi or even both (Ranma 1/2)
Ranma x any crossover female or harem (Ranma 1/2 Crossovers)
Harry x female harem (Harry Potter)
Harry x any crossover female or harem (Harry Potter Crossovers)
There are few things I hate to see in fan fiction.
First: I hate is stories about Naruto being abandoned by his family for they thinking he is a monster, that is beyond cruel in my belief. Those who enjoy this are nuts!
Second: Sasuke, I seen him in both anime and manga, and the manga is his true self. A complete mad dog that needs to be put down. I don't like Sasuke being paired with any girl, he does not deserve any girl. I hate good or nice Sasuke stories, it seems plain creepy to see Sasuke in that idea. But: I do like when he is punished or killed in any story. The only good Sasuke is a dead Sasuke.
Third: I have to see Naruto being banished from the village or simplely abandon the village.
Fourth: I hate seeing Harry Potter abandoned by his parents or used as a tool or being betrayed by his friends. Or him having a sibling who is mistaken as the boy/girl who lived, causing his parents to ignore him or plan abandon him for his sibling. Sure its fiction, but would you like that happen to you?! Couldn't they just have his parents killed rather have Harry abandoned?!
