This could be a hard-mode setting. Add Earth-Mars time lag. Use something like RCS to set up waypoints and autonomous parameters for the rover. Require line-of-sight for lander-rover comms on Sojourner-like rovers. Simulate rover-satellite comm windows. Rovers move at realistic speeds.

This would be a great option to add to the game. We already have two "modes" and this gives people something almost perfectly akin to the real life scenario.
Low priority for me right now, until the rest of the game is solid, but this is something that should go in.
Edit : There are some hard mode features coming. Personally, if they could add as many "hardcore" features a possible, and have them enabled individually, by check boxes at the start of a game, that would be the best.
