Someone will probably take offense to this, but I've avoided traditional airsoft because I have no desire to hammer bad habits into my subconscious. I quit playing army dress-up when I was a kid and the guns I carry these days have the real ability to hurt or get you hurt. Airsoft played for recreation tends to be more about reliving childhood "war stories" than being about teaching you anything worthwhile.
Would it be fun? Sure. Could it be a great team building exercise or just good exercise in general? Sure. For me it's a personal decision. If I'm going to run around with a gun and shoot at things, I'd rather do USPSA, IDPA or take a defensive class. Most Softies probably spend as much on their gear as you'd spend on solid kit for a defensive carbine class anyway.
Now, if someone wants to organize some force on force action where it's geared up toward teaching the individual how to clear their house at night, or how to use cover properly, etc. then that sounds worthwhile. Further, I bet the cost of kitting up for that would be a lot lower too.
YMMV.
