Currently in career overview it shows your reach spartan in front of your chosen halo wallpaper. I thought it would be cool if maybe it showed all of your player models across games. Here is a quick photoshop i did, obviously things like positioning and sizing would be done different and better, but i think this would be really cool and be well suited for career overview, they could even include a halo 2 model of your spartan since they do have all those types of stats. And if they really wanted to go all the way add a small elite button which would change your h2,3, and reach spartans into your elites when clicked.
Seems like an interesting idea. Things could get hairy on the technical side, though… I still remember the plethora of issues that surrounded the Reach renders.
It would also be cool if you could hover and press A on a certain spartan and then it goes to a career overview for that game and tells you your stats for that game.
