Implications of Newtonian universe

I'd like to remove the speed of light limit from my world. However I don't want to just hand-wave the consequences. How should my universe look if:

• light travels at infinite speed, and so do gravity waves and magnetic fields
• there is no limit to relative speed between two objects
• energy cost to accelerate doesn't depend on speed

Would I need to change something else to make such a world work? I am interested in consequences in outer space, space travel and observation of space, rather than consequences on microscopic scales.

To narrow down what I'm after, I'd also like to point out that the world is a game, which involves people traveling between planets in their ships while obeying the rules of orbital mechanics. Therefore I need to know about:

• Does anything change in the way rockets and related tech work because of my change?
• Will the background sky look different? I assume the same amount of light arrives at the observer as in our universe, but suddenly we watch the universe as it looks right now, rather than a million years ago.
