This kit includes everything for 2 people to have a laser gun battle (Guns, Sensors to determine if you've been shot, etc.). I'm sure M would enjoy it if there were enough for 3 or 4 people as well. There are pistols, rifles, sensors etc. sold individually as well so if you wanted to expand the set for more people (full family battle) you could.

David & Melinda and there kids have a full size Air Hockey Table at their house. Our kids played it on Thanksgiving and really liked it. This is a table top on that is probably a better size for them (maybe a little small but only $20).
