Ours (Leighhack) is small in membership but moderately wide. We have textiles, fabrication (3d print & CNC), electronics, woodworking and infra/security in pretty constant flow. We're just finishing building a darkroom.
Yesterday was two members sewing (one dress, one stage props), one member restoring an old Mac and cutting on the CNC (me), one designing and printing a flower pot for a monitored garden. And that's what I know of.
We've just finished up a six week sewing course, and we're looking to courses on 3d design and printing and I believe woodturning.
Different hack(er)spaces have different priorities, dependant on the members and community it serves.
Infocom adventure games are some of the grand-daddy's of text adventures.
Zork is by far the most well known, but also pretty infamous are Hitchhiker's Guide to the Galaxy, Leather Godesses' of Phobos and A Mind Forever Voyaging.
As a warm-up, I'd recommend Moonmist. It's a mystery game listed as a "Beginner" game, and is great for introducing elements of the Infocom system.
