In my save game, difficulty: 1

[WurmD]

Hi,

In my save game I see, difficulty: 1
  What is the range? Is this the easiest one? (If so, I don't remember setting it to the easiest difficulty [not something I usually do])

If I change the difficulty in the saved game to 2, is there any adverse effect in the game? I can continue playing normally?

You can change the difficult in the saved game if you want. The game will work fine.
