IGN is having a cool poll to see what people think is better. I know there are some annoying threads about this specific versus topic but lets keep this to a friendly debate. I'm posting this in both forums as well and am interested to see what people think.
Please keep it to legitimate opinions and arguments. Not just "HUR DUR (insert game) SUCKS". The poll is on graphics, multiplayer, and campaign.
http://www.ign.com/articles/2012/11/21/you-decide-halo-4-vs-call-of-duty-black-ops-2, it has instructions on how to vote. Real simple and you don't have to actually watch through every video.
Graphics- Definitely Halo 4. Cut scenes were great and I thought the opening one was live action at first. In game was still amazing too.
Campaign- Gotta give it to Black Ops. It actually got me playing through more than once. The different choices with different consequences were great. Halo was great and did a great job with the story but overall I enjoyed Black Ops more.
Multiplayer- Halo. Call of Duty has better replay value in my opinion, but there's too many issues with it. I like Halo better because I feel like it is balanced better and takes more skill. If Black Ops didn't have the problems with lag, spawns, and gun balance, then I might have picked it. I do sometimes find myself playing Call of Duty more but I think Halo has better quality multiplayer.
