I love playing foolcraft to a point. Just be warned, I'd rather see something else on the Dogcraft server. Foolcraft requires a tight knit community of players who will be online constantly to continue their work. If people start to falter, you end up with some people who are 10x further down the pack than others. Also, since it's an exploration pack, doing tech trees doesn't really give much in the way of content. After about 2 months, you'll run out of things to tech out of.
I'd much rather see a questing pack with a diverse tech setup but balanced with design.
