The board setup – there’s no more ‘roll for terrain’, you just place the terrain as you like it. I imagine tournaments will handle this very differently, but if you want to set up like an entrance to a city with wide-open areas at one side and a mega-dense area at the other, you can do that. It makes it a little less tactical but for ‘serious’ games you can roll 6th edition style. I think 7th requires you to talk a lot more with the other player to decide what sort of feel you both want for the game.
