Today I finished Finished Jump Ultimate Stars, for Nintendo DS. That means, I got all characters, played all the scenarios in the story mode and reached all the objectives for each of them.
It is a fighting game, but it has a mission description for each stage, that requires understanding. Character names and skills are all written in Japanese. But the most important is that the game is addictive. Specially for this last one, I strongly recommend it.
One of my favorite characters in the game is Allen Walker, wich I knew it was from D.Gray-Man, but I never watched it. Now I'm doing it. It also seems like a nice series. I still not recommend it, but definitely try Allen when playing Jump Ultimate Stars.
