It is strictly an "also ran". The shipped configs had a serious error.
Technically, you can finish it -- the goal was "Bake a cake". But the challenges were wrong.
Instead of vanilla cake, with chickens being exceptionally rare, something (I don't know what) removed the vanilla cake recipe, leaving only Gany's Chocolate cake, and chickens are actually more common (I tried changing the chicken spawn weight from 4 to 1. It wound up with both a 4 entry AND a 1 entry .
Chocolate cake requires jungles. Jungle saplings ... I'm not sure if I put any in the stronghold chest. I know that I put lots of obsidian there, so the unexpected challenge is using a nether portal to leave the starting continent and find a jungle.
There were supposed to be three paths to choose from; due to config file errors, the twilight forest is basically disabled (no diamonds), the nether has neither iron nor diamonds, nor flammable gas (but you should be able to find obsidian in nether fortresses ... did I ever double check that in what shipped?), and the stronghold does have the stuff needed to make mystcraft worlds, as well as obsidian for nether portals. But I think the stronghold path is required.
