Usagi Yojimbo is a rabbit samurai, and the plot is really nice (http://www.usagiyojimbo.com/). Rabbits as humanized characters aren't something original on Lugaru, but yeah, it definitely fitted right.

Lugaru seemed nice to me (actually I ended up donating some bucks and getting the 5 games, even though they went open), just didn't have time to play them extensively, except for world of Goo, which is addicting (but that goes for another thread). :)
