Even though this is simply a FLAME BATE topic, I will respond.
Nintendo had some of the best MATURE titles on the market, ever hear of Eternal darkness? What about the upcoming MGS made by silicon knights, or too human?
I agree the cube could use a good influx of shooters along the lines of timesplitters 2, but to say it lacks mature games just isnt all that factual, and trust me I use to feel the same way you do.
More violent games would be great, but the problem is not with nintendo as they dont make violent games, it is with the third parties not making their violent stuff for the cube.
So lay the blame where it should be laid.
