I was on an 8 hour trip to visit some friends and go to a business meating yesterday and I was bored, having left my book and ipod at home, so naturally I was thinking about H&H and what I could do to have more fun. That is when it struck me, Adobe! or mudbricks would be a great way allow noobs/lazy people to produce better Qulity bricks without having to traipse around the map digging for Q90+ clay.
There are pros an cons to this of course:
Pros:
Basic clay would be able to be turned into better than average clay with the use of high Q straw or plant fibers
Anyone who has taken the time to cultivate wheat will be able to produce better than basic bricks
Alternate styles of buildings can be added with an adobe look to them
Another use for sand, meaning people will actually need more than 29 sand that is currently needed(9 winebottles and a wineglass)
Cons:
Anyone who already has access to high Q clay also probably farms even higher Q wheat, so they's be making even better bricks than anyone else
Due to the nature of making adobe bricks you'd need to add a tool to make them in(something with 2 "fuel bars" one for water, and one for straw, then a window for sand and clay)
If you add adobe bricks you pretty much requires stuff to be added to use the adobe, buildings and alternate looks for stuff made from them
TL:DR
Adobe bricks could be nice if implimented and they'll allow people who can't get high Q clay to make due by farming and using straw in conjunction to basic Q10 clay/water/sand to produce the better Q items needed to run a city.
