Too easy to get gold?

[Lantisu10]

I'm a few hours into the game and I already have 400k+ gold. I remember in armored princess I was scrambling to have enough gold to purchase troops. This made things challenging and fun.

Now I don't even care if I lose a unit. I can purchase all artifacts I come across with ease. The game is really easy so far.

Does anyone else have any thoughts on this? Would restarting on the highest difficulty help?
