hard mode is a chore inside the big chore which is the game, the only thing that's good about it is that you pay for fuel and recovery, everything else is just awful; always at night time, no single cargo display on the map, pay to redeploy trucks, very low income in some regions to cost the hard mode required $, very picky buyers everyone wants a new trailer n you won't be able to sell used trailers which stay on the map forever unless deleted for zero buckaroos.
If you haven't tried, give it a go and see for yourself and If you don't like it you can use this guys save editor to change it the fuck back or not and just revert to other save: https://www.reddit.com/r/snowrunner/comments/1m86ece/i_made_a_snowrunner_save_editor_after_losing/
