Well, seasons will be really different, and length of days will be strange too. Lunar influences, hoo boy.

Mars is actually a *really* fun case as the seasons are affected almost as much by orbital eccentricity as by axial tilt.

So southern hemisphere seasons and northern hemisphere seasons aren't as "equivalent as the ones on Earth. As I recall, one hemisphere has a long, cold winter while the other has a long, cool summer. So even terraformed things would get *really* different.
