When you get to the point where you can you can build the Celestial Tower (this takes level 3 building), lay the foundation and demolish it immediately. This will get you a trophy and trigger a star shower!
Do the same thing with the Lunar Tower to get another trophy and a shower of moons. (I got about 20 of them!)
Want a "Super Tribe"? Use your stardust on a younger male member of your tribe to max out all his skills and attributes. This takes anywhere between 50 and 60 stardust on average. When this "Super Dad" is bred with a female member of the tribe, the baby (or babies) will have 100/100 on both Physical and Mental Strength, regardless of the Physical/Mental Strength of the female. Occasionally, you will get a stray child with 98 or 99 on Physical but very seldom.
The advantages of this are two-fold. First, the "Super" members move really fast due to the high physical strength. Pretty much a dead run all the time. Second, they learn skills at an extraordinary rate due to the high mental strength.
Begin building the boat platform and immediately demolish it. The game thinks you can now build the boat.

It's simple to speed up time in this game. But before you do I want to warn you that you have to set up your tribe before actually cheating this or they will all die.
Make sure no matter what you are cheating for...science points, food, logs, rock...whatever...you have your tribe established first. Make sure your have trees allocated for harvesting and people set to only deal with wood collecting and food collecting.
After establishing a self-sufficient tribe, the left over tribes members you have need to be set to do whatever it is you want to speed up....researching, harvesting trees, construction, whatever it is. So have like 3 members researching and 2 members harvesting wood and food.
Save and Exit the game.
The game uses the Windows clock to setup the going on's while you are away from the game. So simply set the windows clock in advance, and the game advances immensely.
But be wary, the clocks are not on the same schedule, I advanced my windows clock 3 days, and 3 of my 30 year old tribes members were dead when I reloaded it.
After reloading it, simply save and exit, then reset the windows clock back to original time, and your done.
