try to find some visual novel games like steins gate, robotic notes, hakuouki, tears to tiara and etc..
i would also recommend ACE:R, and 2ndSRWOG and some gundam games but that's just me.
I looked up ACE R and it looked like a fun crossover, and it is pretty cheap to import. Any reason not to? --- Know Japanese? Post your advice in the topic below! http://gamefaqs.com/boards/316-gamefaqs-world-japan/63714709
look at the article in my signature. Also Sengoku Basara 3 Utage, or the hd collection of 1,2,2.5 is also really good. JoJo's Bizarre Adventure All-Star Battle is coming out in March, if you are at all interested in the franchise you need this game. --- Servbot #12508 kotaku.com/5920417/why-gundam-extreme-vs-is-the-best-anime+based-game-ever-made
