Thanks for the reply and clearing everything up! I kind of have the same issue with getting ideas after I've already written something as well.
I personally like a pretty large variety of fics. I honestly prefer manga fics the best because the characters in the manga are my favorite. I also tend to stay away from fics that are like....Ash harems. I honestly don't like Ash all that much, so I prefer to read away from him in general.
I've enjoyed rewrites of the canon storylines (for instance, somebody rewriting the RSE game storyline with their own touches or something).
AU fics tend to be some of my favorites because they have so much possibility and there are so many ideas to explore. It's interesting seeing what kinds of changes people would make to the anime, the manga, or the game if they had the choice.
I'm a little more hesitant about all-OC stories (although creating OCs can be fun) because I don't have any kind of perspective on the characters prior to reading and it makes judging the story itself more difficult. I don't have anything against it, really. Some can be really well done and I even like attempting to write them myself, but for reviewing purposes, it is a little bit more of a challenge. Not to mention a majority of OCs kinda turn Mary Sue-ish.
As for writing, I plan on doing AU, maybe a rewrite or two, and maybe a OC-ish story....kinda. IT's really more what comes to mind though.
