I have 3 teen boys... Gaming with them is as much for fun as for the regular bonding. We also work on DIY projects (construction/welding/electronics), car mods and maintenance, MMA (TKD, MT, BJJ), traditonal sports (basketball, soccer, american football, volleyball, ice hockey), 3D design/RC Cars, card games, etc.
Its just another way to spend time with them. Before I blink, they will be grown and out of the house. Every moment that I have with them at these ages is gone way to fast. Don't limit yourselves - body and mind.
