We tried something new last night, inspired in part by the "no huts" variant of Early Landings, which seems to have really captured (2)'s imagination.
On top of our normal 'House Rule' of a Spotless reputation we imposed the following hut-popping regulations.
Before founding - anything goes
After founding - the only acceptable outcome from a hut is Barbs, Gold or Nomad - if anything else appears you must reload and re-pop until you get gold (any amount), Barbs & Nomads are no longer acceptable
This lead to a very interesting game - the upside was that we had more control over our tech tree - the downside was we really missed the extra units and advanced tribes
Try it out and comment please
