There are games with souls on the wii
id argue that wario ware has more creative soul than 90 percent of games
i do agree that wii zelda sucked, but i love the system, and id say many games on it have more soul than the examples you gave
wii sports is a 2 player game, last night i played tennis again with a freind and believe me that game session had passion and soul ;) a ton of fun i cant have playing say ff7
