I hadn't played any of those before and found that if I put in the easy mode without time limit they're good fun ^^ - Vision in White has excellent voice acting and the people look very similar to how I imagined them in the book and Tiger Eye is a mix of puzzles and hidden objects and while the art is not as great it is spot on in the voices I thought.

I wish the two games had sold well enough for the sort-of-promised follow-ups but so far no luck...
They are for PC, as Kate Nepveu points out.

Also - I played Sakura Wars on the PS2, so I don't know what hell they put you through on the Wii ^^
