Been playing 31.16 since it came out, only just started playing 31.2x, and only as an adventurer, and now I've moved to 31.23 and started trying to find a site for my first fort.
You probably know what comes next.
I don't understand the decision to omit the rock layer names completely, in hard code no less. The geology aspect of embarkation was one of the things I really enjoyed, and it's gone now. I was really looking forward to the new build, but I just can't imagine finding a site I'm comfortable spending hours and hours on this way. It would have been really nice to have an init option to use rock layers, but not even that concession is in there.
I'm reminded of my feelings towards the original Assassin's Creed and Far Cry 2. It seemed like the makers of those games were making something groundbreaking and fantastic, something the game industry never had before but desperately needed, and actually surmounted the technical challenges of pulling it off. Then, for some inexplicable reason, they said: OK, now that we've constructed something completely awesome, what unnecessary things can we do to compensate for all the win we just put in, and bring the game back down to average? In AC's case, it was repetitive missions and brainless combat. In FarCry 2, they took one of the first true open-world FPS engines and then made the world a series of canyons just like every other linear FPS before it, with AI that didn't recognize friend or foe. These acts were needless backsteps that negated much of the progress made by the immediately preceding forward leaps, and they robbed the world of the games that those titles and others like them could and should have been.
Something similar has happened here. This change did not need to happen, and it has made parts of DF less than what they were before. Part of the wonderful detail and arcana that makes DF what it is has been removed. Before, it felt like you were conducting a geological survey on the embark screen to make a guess as to what you would find there. Now there's no way to know.
Thankfully, unlike Ubisoft's acts of self-sabotage, the addition of fail or the removal of win to DF is reversible. 31.16 is still there, with all the save files and custom settings of the last few months, so I still have that. I hope Toady will see fit to restore rock layers in embark in the future, like we continue to hope he'll restore other things we've lamented the loss of.
I understand I may be in the minority here, but there do appear to be those who agree with some of what I've said. I know that many of you do not consider this a problem. Before you tell me that you don't care about the changes, I know. And I would remind you that the fact that you don't care does not change the fact that some of us do. You are perfectly free to continue not caring, and I would assume that if the feature does get restored it will not affect you because you will likely continue to not care.
