I just produced Gold and Supplies to research
I have not that many goods, but now i have space for it and started.
And the fact, that i have hollydays and just built stilt houses with the 15 per 15 Minutes gold (with 120%) helped a lot.
I researched the better road in the bronze age as fast as possible and used the diamonds given by quests to buy the 25/square-premiumroad (now i have 8 tiles of it).
So i just figured out the best and most effective way, and that every 12 hours (includes a complete regroup of all my buildings usually)
So, yeah, YodadaJew is right, it is possible, altough it recquires a lot of simple maths and tries to do it
