I just have a problem when people start saying this Halo 4's UI is bad when there is no user experience to base it off. Art isn't something I feel as though people can or should ever "hate". There are many people who consider UI design or UX design to be an art form of sorts. This UI cannot be judged as an interface until people interface with it. It's just silly. I haven't ever really sung Halo 4's UI any praises either.
It's the blanket statements which irk me. They're silly.
Take the verse of any song and tell me the entire song sucks as a result. In UI design especially, a single screenshot isn't a lot to go by. Where do the menus go? How does the user go from each item on the page? Like, if I was to scroll to the end of the friends list on that screen and press up, would I be on 'Start Game'? How nested are the features most people will use?
Do we even know if the Active Roster had previously been hidden before that screen? What I mean is, could it be a "Press X to toggle between Current Party and Active Roster" deal?
I can't say I love it and I can't say I hate it because I do not know it. Does anyone? It's not much different to how I treat newer members here. I won't dislike someone until I know them enough. Just because someone makes a first post that is so hilariously bad doesn't mean I can say I outright hate them. That's just me. So I like to live positively, or at least, positive until proven otherwise.
