Oh yeah. I am not a fan of dragging things out, which is probably a large reason why Sony doesn't have many (if any?) super long running franchises. I'd prefer them to stop making games for a series (even if I love it) than to keep making them as they steadily decline in quality. :(

That said, while I haven't really PLAYED any Nintendo titles in a long while (last game I bought for my Wii was probably Brawl, tbh) I don't think they've gotten to the point of the gameplay being old? ...and I don't think the platformy games are as story heavy as a lot of the titles I enjoy.
