Madden and all those other sports games need to end. Or at least just offer roster updates as a patch/dlc instead of coming out with a "new" full price game every year. CoD doesn't need to end, just needs to do something interesting. CoD4 was great because it shook up the series pretty well. They should do something like that again. Halo, actually looks like it might be interesting, now that there's a new developer involved. They could take it in an interesting direction, but probably not. Fingers crossed though. As for series that should just straight up end, Sonic needs to be taken behind the shed and put out of its misery.
