Gameplay was way different. Since my favorite play was to steal ships, I feel salvage corvettes getting the bum's rush was a mistake. The auto load out of the next chapter's enemy's fleet auto-scaling to what the player ended up with was a turn off as well. Sometimes I actually enjoyed taking a break between scenes and letting the collectors harvest at their own speed... if memory serves, there was a button to auto harvest in HW1 if you so wished?
