As far as mature people liking it...I'm a med student and I'm very happy with the system so take that for what its worth. Also I know there's more mature games such as Sadness coming out in the future (others too). The graphics are good...nots as good as PS3 but I like them. So far I own three games that I love other than Wii Sports (also great)...Zelda, Elebits, and Trauma Center. I think its worth it...inexpensive, fun, and great games.
