I don't like the UI either but yes it's about to change in the coming months also MS should do a better job for install speed since it's atrocious. It took forever to install Forza 5 and Dead Rising 3.
I get your point about showcasing what the console can do and ofc HaloCE isn't the best game to showcase it's power but I don't think anyone expected that. A remaster of a remake can only do su much. Try Ryse Son of Rome. To me it's still one of the best looking games available on consoles to date.
EA Access is also a great way to have access to more games. Now that both Titanfall and Dragon Age Inquisition are in the vault it's difficult to pass by.
Anyway congrats on your purchase, I recommend you grab Forza Horizon 2 if you like racing games it's the best imo.
