Anyway, I'd have to say that the only series I want to end (at least right away) is Mass Effect. It is perfect as is, and should be neatly wrapped up and shelved for future generations to look upon: how you do a branching story right.
While I was somewhat disappointed in 'S Creed: Revelations, I know that was just a temporary case of Ezio overstaying his welcome, and I also knew the series wasn't going to stick with that particular setting and style for good. I'm waiting to see how 'S Creed 3 mixes things up before I form an opinion on whether or not the series itself should go. If it's a nice step in a new direction, then all is well. Should it fail to mix things up beyond a ctrl-c/v and re-hash of the past engine, then I'll be calling for the series's terminus.
I know there are people out there who still enjoy the sports titles, but they should definitely cut back to, oh... one every four years per sport. That seems to work for both the seasonal Olympic games. Give them time to develop and mature properly between each rendition before anything else.
Halo. Ooh, that's a tricky one. As someone who walks the walk and talks the talk, I say Halo's multiplayer has gone long ways since Combat Evolved. There have been tweaks in the transition to 2 and 3, and a ground up re-haul for Reach. When I play, I feel the difference, and I am most eager to see how this new Halo trilogy intends to stride.
Since the Chief doesn't have much of a personality outside the novels, I don't have a problem with that cardboard prop making a re-appearance. He's a pretty good icon for "I shoot things," and that's really all that's needed. He stays unobtrusive, lets his AI do all the talking, and doesn't afraid of anything. If I wanted good characterization, I'd play Mass Effect. If I wanted a nice and convoluted plot, then I'll strap into the animus. If I want to shoot things with my online buddies, then the Halo ring is the place for me. It recognizes its niche for accessible multiplayer action, and doesn't try to be what it isn't.
Sonic and the various Nintendo titles have their own communities formed around them, and are still enjoyable if repetitive. As someone who never had much stock in them outside of Pokemon, I say let them keep going.
