Speaking of difficulty, what exactly gets more difficult when I increase the difficulty level of the game? (ie. what changes if I choose Davy Jones instead of Blackbeard?)
I played my first game on v0.98b, Blackbeard; and now I'm playing my second game on v0.99, Davy Jones. It doesn't really seem significantly harder; but the base management side of things is much 'faster', for what of a better word.
In my first game, I had a shortage of money throughout pretty much the entire game; and also a shortage of armour parts, and a shortage of... well most stuff actually. When my money situation improved, I was using money to buy tac vests so that I wouldn't have to spent my precious armour parts. Also, there were a couple of points in the game where my research outpaced the available research topics (and so I was down to just research data disks, with nothing interested to go towards. I think the research bottleneck was mostly because it took ages for me to see any academy missions - so I guess that's a side issue.
Anyway, in my current game, I've got a huge stockpile of armour parts that I don't know what to do with; and I've got big heaps of gold bars and credit chips in my base that I haven't needed to sell. And the research tree has been wide-open for a long time. I think I've got all the resources that I need to get me well into the late-game tech.
It seems to me that the main difference is that the enemy's tech progresses a bit faster; and so I'm seeing more armoured enemies, and more enemies with good weapons. But I'm not sure if that makes it significantly harder. If I win a mission against well equipt enemies, then I get their equipment. Which means I get way more money, and more stuff to research, and more armour parts / power armour parts / grav units etc. So although it's a bit harder facing stronger foes early, the difficulty doesn't last long because it creates a turbo-boost for the player's economy. The stronger weapons from the enemies can be used to defeat their stronger armour; and everything has a high sell value. The only thing is, I'm not sure if I've got heaps of money because of the difficulty change, or because of the new early-game missions (which have provided me with many many apples). All I know is that I'm getting my 6th base far earlier than before; and the bottle neck for building study rooms is just the construction time - not the money or resources.
In any case, I'm curious as to what gets harder on harder difficulty levels; and I'm wondering if I could make some tweaks to the system so that it could be harder without the game being shorter. (eg. maybe less of an increase to enemy tech progression; and a percentage increase to all maintenance costs, or decrease to all selling values; or perhaps a small reduction to the rate of experience gain for the player's soldiers.) I'm just throwing ideas around. I have no strong opinions about this at the moment.
