Art: Painting, sculpting, pottery, etc. Is very theraputic and allows one to wind down. Take their mind off things and just concentrate on the art work at hand. Plus, it can be shared with the rest of the House by displaying in the various rooms. The pottery could be made as usefull every day items.
Music: Listening, composing. playing and conductiong small bands or orchestras. All can be used to relieve tension in most people. Plus, they could be at sporting events adding music much like bands today at shool sports.
Sumo Wrestling: Doesn't need much room except for the audience. See who can push the other out of the ring first. Simple enough, right?
Dung Bettle Racing: Speaking from personal experience in Desert Shield and Desert Storm (retired Army) this really worked to take our mind of things and needs very little room. Get a bunch of dung beetles paint a number on back, put in jar. Then in the center of a 4-5 foot diameter circle traced in the sand you turn the jar upside down and pull it up spilling out the dung beeltes. First one out of the circle wins. We had bets and such like horse racing.
Games for the kiddies: Bean Pod Toss, Dunk the "robot" (person disguised as one), Wreath Ring Toss at sticks, (well you get the idea)
Darts: Especially at the Pubs. Wooden carved darts with super-tough thorns for points and feathers for fins, if possible. If not, stiffed cloth or stiff plant leaves cut to specs. Dart board of soft pine, cork if available. Possibly some kind of self-healing soft wood. One would need to practice strength control as not to smash the stuff.
Bowling: Not the traditional alleys today. Just some hard wood pins and a few smooth rounded small boulders. Like the sport orginally started out. All you need is a relatively smooth floor about 30 feet long and mark out approach lane and boundry lines on the floor. Don't forget the ole pin boy. This could be a family sport and league tournaments as well. One rule: throwing the boulder or smashing the pins to bits is a definite disqualification. This would teach strength control as well.
These are just a few off the top of my head, Enjoy
