I personally don't recommend trying to do the tasks for this game. I thought it would be feasible to do it, since this is basically just another clone of those timed city builder games. However, the way this one is balanced makes it excessively difficult to achieve the tasks without spending real money.
The rate of resource accumulation is very slow relative to the costs of research and production, compared to other similar games. Once you get to around level 9 or 10 on your buildings, it takes about 2ish days to accrue the resources necessary to begin a building upgrade or research project. The problem is that in that time you are likely to be attacked by other players who will steal your resources. Getting enough troops for defense will take away from the resources you would use for building or researching, and there will always be someone at a higher level than you who just has superior troops.
