The so called "no-loss" concept (whole game) is wrong and stupid.

No reload challenges can be fun too, though combining with no-loss is pretty frustrating. The idea that you'd have to start the game over just for having some mage cast fire arrow at a bad time is... ugh.

Restart game , why ? You have autosave in castles, and after traveling to new islands. No need to new game, just reload last autosave from getting to island you are currently at.

@ Fatt_Shade – cue words here are: no reloads of any kind.

How about new challenge: turn off monitor!

Some achievements are only available if you lose units (at least one).
