Personally, I'd get a little sad remembering all the times my and my brothers played Mario party, Toy Story, and even when I soloed my way through Ocarina of Time and Majora's Mask. They're a good company, but reusing successful franchises won't help much longer much to my dismay.

I doubt that it would, but in my personal opinion, I would like them a lot more if they didn't make every game based around their more known IP's. Like make a new kind of game with a new fresh face to enter the fray, and pave a new road. Like for instance, I loved the concept for Super Mario Galaxy, but the only problem I had with it was the fact that is was Mario; This was the perfect set up for a new fresh character separate from their others, but no, they did marty-O.
