I agree with the both of your opinions. For example, Yoyolary, i have always wanted there to be an element of gravity to be controlled, as you mentioned. Also along with what you said about the different physics settings. I however belive that in the game halo 4, it would be nice to see a more classic experience in some ways. Such as bring back past vehicles like the elephant or since the plot is set in the future even including things like portals in the campign but a new type of portal where you can teleport through time and space. Also it'd be nice if you could:
a) Link maps together by portals or a thing of such
To be able to set up a map queue where you dont need to change the map everytime but rather, it would cycle through a list or even a "custom playlist" of maps you made that go together and then you can play that way I would be interested in hearing your opinions on this,
Thanks
