[Difficulty & In Game Input]

I 100% agree

[Not able to change difficulty in game]

I agree-you should be allowed to change difficulty.  It seems natural that you would start at a lower difficulty and turn it up after developing skills and knowledge of the game.  It seems nonsensical that you would have to completely restart and lose any hard-earned building progress only because you want more of a challenge.  And to the argument that this would pose an “exploit,” who cares?? This isn’t a competitive game, it’s purely interactive: jump in, farm resources, build things, and enjoy the story missions and BurgL quests.  That’s where the longevity lies...I’ve personally invested about 50 hours into building a small network of bases in medium difficulty without knowing that you couldn’t change difficulty (thanks, game) .  Disgruntled, probably time to pick up rocket league again.
