Alrighty mates, I'm here to call shenanigans... The embark menu might want to be rechecked. Before I go any farther into this I'm only using one modded in metal of my own creation and the Mayday graphics upgrade.
I modded in a new type of metal that is 10% weaker than iron. I went and fired up DF and tried to embark. I looked at my stuffs and noticed that my anvil made from the new metal (micraz) was actually cheaper than the 1000 point iron anvil. It only cost me 900. I said sweet and began to spend my remaining 200 points. I thought to myself later that since my metal is so common (smelted from microcline) I should lower the price and effectiveness some more. I delete my fort and embarked a again, sweet the price went down at the embark menu again, this time at 700. I went on to spend my remaining... 200 points? Wait what?
Try this yourself. Mod in a metal that is cheaper than iron that you can make an anvil out of. The game will give you the cheapest anvil it can, and no sort of retribution for it being cheaper. You still get only 200 extra points.
Now some of you may be saying "It keeps it balanced" Yeah I don't think so... If I take a hit on quality and still get the same number of points as the dude who didn't, why take it at all?
My little rant is over, just pointing something out that should maybe be fixed in the next version. Use a standard number of points for the embark screen or something. That's all folks... If I missed something or if there's a easy way to change the embark points to be a set standard number let me know.
