I hope the Xbox Live play lists allow more freedom than previous Halo games, its always bugged me ive wanted to play Big Team Slayer, then in the big team playlist i can only play slayer if enough people vote for it.
Ive been loving system linking the game on XBConnect, i just have a feeling i'm going to be dissapointed with Xbox Live games, especially as normal slayer looks to be limited to 4v4 from the live streams i have seen. 8v8 is where its at!!
