The HW1RM campaign gives far too many resources. I’ve seen a couple of posts by people showing them with a maxed out fleet sitting on 37k+ RUs towards the latter half of the campaign. That’s enough RUs to rebuild your entire fleet several times over, far more than could ever reasonably be used. This is way more than in the original.
The original game wasn’t designed with auto harvesting in mind. I think the resources really need to be looked at. In the original game, I always made sure to harvest all resources and by the 14th mission I had a fairly large fleet, but not maxed out, and I was out of RUs. Preserving ships and managing resources well was a big part of the original game. The resources need to be adjusted to match the spirit of the original game.

The HW2RM campaign does the same thing, though this imitates how HW2 classic worked. It still gives far more resources than could ever be used by the player, and I think it should be changed, but that’s just my opinion.
