I'm dedicated to Halo, I've been around since day one xbox CE and I'm outspoken on B.net and Waypoint etc. I'm not worried at all. Game has been out a 5 or 6 weeks and it's now XMAS holidays plus the developer has plenty of early next year updates, weekly changes and have stated ongoing support.
I have fun with Halo 4, just like I did Reach, just like I did 3 or 2 or CE. They've all had their + and -. Sure my friends list over the years has more COD games when they're online but the same core friends I played with in previous games are the same I'm playing with today. Why those same friends? Because we're all happy with a new experience each game and realise it's about the fun of competition, not just competition for the winner skilled sake all the time.
Sure some smaller maps, tweaks and classic iterations but that's coming so what's the big deal right now? Some features to get patched, ok so it's not perfect but no Halo or video game has ever been that way, so relax and have some fun with your favourite franchise.
ahaha dude I know, it's like, all these tryhards just criticize all day, and I'm here having a blast playing Halo 4 on the 360 that's installed in my Ford Truck while I blast Breaking Benjamin and chow down on beer and pretzels
