Just downloaded this a couple days ago, and I've been having a ton of fun! I like the tools/challenge of building a wooden, above-ground fort, and the research requirement for most of the mod-specific builds is something far different than Vanilla. I also have to say I really love the odd-sized buildings like apple trees/q control, the bigger-than-average weather factory and library, and the truly massive Rainbow Refractor I've just gotten around to building.
A few things to note...
1: The manual says 1x Cloud is condensed to 1x Heavy Cloud Block. With the latest main download, this actually takes 2 clouds. It also says 1x cloud dilutes to 1x Light cloud -- I haven't had a chance to see if this is accurate.
2: The Rainbow Color Extrapolator seems to consume any tool, rather than its proper blueprints to be built -- I could have selected a simple page.
3: This might be based on the graphic packs, but some of the likes on the thoughts screen seem a bit scrambled up...
4: When ordering seeds from the outpost liasion, "Radishes" appeared twice.
5: I seem to be able to plant "Turnips", but the manual's got nothing to say about them.
6: This might be DF and not the mod, but Ponies don't seem to collect refuse, even if it's "inside" by virtue of there being a constructed floor a z-level above, despite me having a fine Refuse Pile. Do I have to turn on "Gather refuse from the outside" to collect any above-ground?
7: Before I invest heavily in it, it would be nice to know how crystal items, specifically swords and armor, match up to their metal equivalents. Are they equivalent to Iron? Steel? Or should I stick to conventional metals if I have the higher-end ones.
8: Clouds and Pages currently have quality. Nopony's gone insane from having her awesome cloud harvested for seeds or page turned into a chapter, but it seems odd that this exists.
